Sean Carroll channels Giordano Bruno

Sean  M. Carroll, a noted cosmologist, in his first column for Discovery Magazine called Welcome to the Multiverse writes that the progress in cosmology has forced cosmologists "kicking and screaming" to accept the Multiverse, the same theory that caused Giordano Bruno to be burned at the stake in Rome in 1600.

Sigh.

I sigh because the two pieces of evidence that have dragged him "kicking and screaming" into multiverse theory are "string theory" and "inflation". And what you should immediately ask, is "What!? Not Bruno's universalism??" because both of those "theories" have about as much to support them as Bruno did.

Carroll knows this, and in a clever twist, argues that like Bruno, we should explore scientific heresies with an open mind. Except that it isn't the Church, but the philosophy of science that is being trashed. That is, while I am all for exploring scientifically heretical subjects, I would prefer to do so on empirically sound foundations, which neither String Theory nor Inflation possess. One should read Bruce Gordon on the metaphysics that undergirds both theories--which have gone through numerous modifications as they fail to conform to data. In fact, on Lakatos' analysis, both StringTheory and Inflation are clearly "degenerate science programs".

So how does one get "forced" by degenerate science programs that expend all their disposable hypotheses on shoring up the main thesis?

By accepting the same main thesis. And what would that be?

The same one Bruno had--human autonomy and moral relativism. This was Stanley Jaki's complaint in his book God and the Cosmologists when he critiqued inflation, and it is the same complaint Bruce Gordon has about "multiverse" theory.

The main thesis, the whole theorizing effort is an attempt to shore up a discredited philosophy based on eternal particles moving through the void. It has been the same goal of Democritus, Epicurus, Lucretius, Newton and Darwin, which goes by the moniker of Materialism. Because Materialism has no Creator.

In the case of Inflation, it is an attempt to explain the enormous amount of information in the small-scale Earth coupled to the "flat" or informationless distribution of matter in the Big Bang. One of them must be an illusion, and inflation has gone through multiple versions that attempt to find a spontaneous answer to flat space-time that is highly contingent. As Bruce Gordon observes, it is completely dependent on fine-tuned "inflaton" forces that are even more contingent than the Georges Lemaitre's Big Bang cosmology. The goal is to replace the contingent Creator with a self-emergent autonomous contingent creation.

In the case of StringTheory, it attempts to modify these point-like particle things into 2-D strings or n-D "branes", but the intent is the same--to find something that is eternal and unchanging and mindless. The appropriation of "landscape theory" to "inflation" is an attempt to make each "inflaton"-generated Big Bang a different flavor of string, so that every possible flavor (10^500) is expressed. Why? Just because, like Bruno, this eliminates the need for a Creator again, replacing it with a cosmic Monte Carlo casino. Since there is absolutely no evidence that a casino is a better model than a Creator, I prefer to call this the worship of the "Chaos" god, who shows up in Greek mythology only to be vanquished by the Olympians.

The subtitle on Carroll's piece is "Could our universe be just one of a multitude, each with its own reality? It may sound like fiction, but there is hard science behind this outlandish idea."

Is Sean Carroll's physics really "hard science"? Hardly. No more than Bruno's physics was "hard science". And Carroll knows this, because he gives his doubts on his blog, just not in his essay meant for mass consumption. We have one story for the plebians, and another for the Intelligentsia. Because there really is no difference with Bruno's time except that we've reversed the roles of the Church and Heretics, with the Heretics (Intelligentsia) now running the State. The only ones likely to be burnt at the stake are now those scientists who insist that science conform to reality. (You think I'm joking? Blasphemy against the Trinity of Darwin, Anthropogenic Global Warming, Newtonian Materialism will get you fired, pronto.)

The sad part about Carroll's piece, is that it confirms one of Jaki's hypotheses--that what stopped the science of the golden age of Greece, what stopped the science of the Chinese or the Babylonians or the Caliphate was not politics, not anti-science reactionaries, not an epidemic of stupidity, but bad metaphysics. Bad metaphysics can turn any "progressive science program" into a "degenerate" one, and this infatuation with multiverses is sucking the life of hundreds of grad students, the resources of a hundred tenure-track cosmologists into the impossible task of predicting the unobservable.

They'd be better off studying theology.

Hard versus Soft Science

When is a theory a theory? Long ago we  commented briefly on the Climategate revelations that the global warming books have been cooked to support the theory. There are a great many blogs dedicated to tracking how that miserable field is regressing, so I have felt no need to beat an obviously dead and cooling horse. But physicist blogger, Lubos Motl, questions why a 2-sigma result (1:20 chance of being accidental) of climate warming (a highly contested result, not supported by data contends Roy Spencer) should cause the American Physical Society to claim "incontrovertible proof" when a 6-sigma result  (1:Million chance of being accidental) from a neutrino detector is doubted by all concerned.

In effect,  Motl, makes the old argument that there are "hard" and "soft" disciplines within science, and that "hard" scientists tend to need more sigmas in their data, but also give much more significance to the "priors", the body of evidence that support a theory. So when a well-established theory is contradicted then "extraordinary claims require extraordinary evidence". (I'll come back to the strange origin of that phrase, and its degenerate character.) However, Lubos goes on, the "soft" sciences are so squishy, that one never gets better than a 2-sigma effect, and so the criteria are much lower by comparison. By the same token, there isn't much benefit in promoting a novel theory in the soft sciences, say, by imposing a tax on everyone, because these theories are so full of exceptions and prone to reversals. While one would hope that climate science is eventually going to be a "hard" science, the field is young and still quite "soft", which is why Motl sees the exaggerations and politics surrounding climate warming as so egregious.

My own view is that the "soft" sciences are soft for a very good reason--they involve humans. Psychology, psychiatry, sociology, political science, economics and yes, predictive climate change all involve people and populations. Since people have this annoying habit of behaving irrationally or more precisely, obstinately, (where they know the prediction and therefore do the opposite), there can never be great certainty to any process involving them. (If you are callous enough to think otherwise, then imagine that your own theorizing can be predicted accurately, then your own theory turns out to be ho-hum obvious, and you didn't need to waste our time making it anyway, much less the PhD you wrote.) The circularity of the "soft" sciences can be vicious if you pretend they are "hard".

In the case of global warming, the danger sign was including the adjective "Anthropogenic", as in AGW. Once we include humans in the mix, the theory becomes more volatile than nitroglycerine. And this is where Motl and "deniers" claim that the theory parts company with the "hard" sciences.

Even if we have to write off the "soft" sciences, at least we have recovered the objectivity of the hard sciences, or have we?

And here is where I part company with Motl. For it is true that numbers are far more compelling in the hard sciences, but it is also true that the numbers don't vote, don't write textbooks, don't teach, and don't blog. And while the theories may be quite firm and not at all circular, the same cannot be said of the making of the theories. That is, theories don't write themselves, and since theorizing is done by humans, any concerns or worries about theorizing is now just as "soft" as sociology.

Is this a problem? I mean, humans are involved in say, the making of chairs, but that doesn't prevent us from sitting on them, does it?

No, not at all. The problem isn't with the chairs, the problem is when there's a sociological upheaval and chairs get redefined. While the "hard" science remains hard and quite independent of the people who made it, the definitions could change and make it very difficult to sort out the hard from the soft. For example, at one time it was thought that seeing through walls was a supernatural gift and clearly "soft", but the discovery of x-rays redefined the field as "hard". Contrariwise, the study of "animal magnetism" was probably once a "hard" science that has since gone "soft".

So let's take a "hard" science like physics, and ask, what is the status of "string theory"? Is it "hard" or "soft"?

This is the topic of a most interesting paper that evaluates string theory with four modern philosophies of science, which is what the serious study of hard vs soft science is called. The author runs through the criteria, and concludes that the theory fails at all four, making string theory about as soft as AGW. Here's the four views and how they stack up.
Phil. of Science
 What is a scientific theory?
 String theory is:
 Positivism  Verifiable theory
Not verifiable
 Popper  Falsifiable theory
 Not falsifiable
 Kuhn  Incommensurate paradigm
 Not even incompatible
 Lakatos  Progressive vs degenerate
 More likely degenerate
To recap the history of the philosophy of science, the Vienna Circle and logical positivism said a real scientific theory had to have data validating it, it had to be verifiable. Yet theories such as Marx's Communism, Freud's Psychotherapy, and even Darwin's Evolution seemed to be constantly validated without any data ever contradicting them. Thus Karl Popper parted ways with the Vienna Circle, and said that a real theory had to permit or even require that it be invalidated or falsified by some data. This led to the problem that some theories seemed to be in principle unfalsifiable, yet they otherwise functioned as fine scientific theories. Thomas Kuhn was a graduate student of a Vienna Circle member, who was given the task of defending the verification thesis by examining history. He came to the conclusion that the same data supported two opposite (incommensurate) views (paradigms), and thus the victory of one theory over another was sociological--one group of theorists died and another rose up to take their place. Imre Lakatos didn't think the various paradigms had to be incommensurate, Einstein's theory of gravity didn't deny Newton, it merely augmented it. However when a theory spends all of its time making ad hoc excuses to explain unexpected data, then the theory is in its "degenerate" phase, whereas a theory that is explaining more and more similarities with the same set of models is in its "progressive" phase. It is the greater explanatory power of "progressive" theories that makes them superior to "degenerate" theories, and how they ultimately triumph.

String theory, according to the physicists who wrote this article, is empirically degenerate but theoretically progressive. I'm not sure this distinction has any meaning. If one doesn't worry about the data, then how does one know if all these ad hoc rules are brilliant development or just epicycles? But Lakatos only suggests that one choose the more progressive program, and if there is only one program then there is nothing to switch to. The authors suggest that this is the case for string theory, there just isn't any alternative--which I find an odd position to defend. There have been many alternatives, most of which are neglected because all the money is in string theory right now.

But the process of deciding what was a "good" theory made me want to apply this to Darwinism. Here's how it shapes up:
Phil. of Science  What is a scientific theory?  Darwinism is:
 Positivism  Verifiable theory
Not verifiable
 Popper  Falsifiable theory
 Not falsifiable
 Kuhn  Incommensurate paradigm
 Not even incompatible
 Lakatos  Progressive vs degenerate
 More likely degenerate
Strangely enough, all the same arguments apply to Darwinism that applied to string theory! Like string theory, it isn't verifiable, or even falsifiable. It is not even incommensurate with any other theory, because it tries to be everything to everyone. When difficulties arise, say altruism or convergent evolution, it makes up rules to handle all the exceptions. So it operates as if it is in degenerate mode. And people are fond of saying that despite its faults, there really is no alternative to the theory that might be more progressive.

So if this be the mode of the 21st century, science will be inundated in "grand unified theories" that suck up all the resources without making much progress--hindering the development of real alternatives. Which brings us to the phrase "extraordinary claims require extraordinary evidence". To my knowledge, the statement was first made in 1976 by Carl Sagan in his own defense. He was a co-investigator on the mass spectrometer experiment on Viking that failed to find life on Mars. His civil engineering colleague, with a spectacularly simple instrument (the Labelled Release) did find life. Since it was informally thought that the discovery of life would be an automatic Nobel Prize, Sagan had to explain why his PhD-loaded team didn't find it but a civil engineer did. So Sagan intoned this famous line, but of course he reserved the right to decide whose data was the more extraordinary. And no surprise, the status quo was upheld. This is what Lakatos called "the protective belt" of ad hoc statements to protect the theory. It is a sign of a degenerate science program.

Kuhn may not have been surprised, but Lakatos surely would have been disappointed.

Gnunglish

biassed Every once in a while, more often when I am writing a thesis, I get on a rant about Microsoft. This one came up when my erstwhile editor flagged "biassed" as misspelled. Why did she flag it? Because MS put that wiggly red line under it. And why did they flag it? Because I violated the "Rule" of American English editors. Who are these "American English editors"? Nobody knows. I mean, in France they have the "Academie Francaise" and apparently, many countries have a body of graybeards whose job it is to admit or deny words. From Afrikaans to Yoruba, there is a committee who fixes the spelling. But glaringly missing from this list is anything English. Or American for that matter.

So who gets to make up the rules that Microsoft uses for its "English spelling"? Their committee on "Natural Language Group". And who does this group answer to? Apparently no one but their bosses--which I suppose might still be Bill Gates. But no one can tell, because the spelling dictionary file, Mssp3en.lex, is locked in a proprietary format. We might surmise, however, that the now-discontinued Encarta Encyclopedia and Dictionary, which has been spun off to Webster's International since 2006, might be the source of the spelling regulations. And who listens to Webster International on this subject?
Websters' major clients and partners in the digital and publishing worlds have included — in addition to our extensive contracts as a preferred vendor for Microsoft/MSN — Channel 4, Cranium, The Economist, The New York Times, World Book, Dorling Kindersley, Hachette Livre, Harcourt, Rodale and Macmillan
So the cabal has a long reach into the publishing business. We note the presence of "The Gray Lady" as well as two large book publishers. The significance of these for-profit companies will shortly become apparent.

So what in particular is the reason for rejecting "biassed" as a proper spelling? Microsoft won't say, of course, but after some strenuous sleuthing, here is what "The English Spelling Society" says about superior American spelling:
With phonics now officially acknowledged by the British education authorities as central to literacy acquisition even in such a wayward alphabetic system as English, Britain should also acknowledge most American forms as better suited to the phonic learner than their British counterparts.
And here is how the spelling society views the problem that initiated this blog--the doubling or lack of doubling of final consonants:
One of the most troublesome features of English spelling is the lack of reliable rules to tell us when to double consonants. One often cited rule has it that, when a base word ending in a single consonant letter adds a suffix beginning with a vowel, the consonant is doubled if its preceding vowel is both short and stressed (eg, commit has TT in committing); but where these precise conditions do not apply, the final consonant is not doubled (eg, single T in commitment since the suffix begins with a consonant, and in inviting since the preceding vowel of invite is long and the T is not final in the base form, and in visiting, since the vowel immediately preceding the T in visit is unstressed). This rule, which is generally accepted by both American and British spelling conventions is in itself too complex to be easily mastered, but British (not American) spelling aggravates the difficulty with numerous exceptions. The most widespread pattern of exceptions affects verbs ending in an unstressed vowel plus single L, such as travel.
An editor, who must have been reading from a resource I haven't found on the web, once told me that the American approach to doubling was to use the shorter spelling if it did not already exist in the dictionary. So for example, "bus" plural goes to "buses" rather than "busses" because there is no item "buse" in the dictionary. On the other hand, "fuss" does not go to "fuses" because there is a "fuse" in the dictionary. (What this rule does with "buss" is obviously a bit unclear--Microsoft certainly rejects "busses".)

Well let me clear up what the Spelling Society finds so difficult to understand. The spelling rule for doubling really is quite simple, and applies to ancient Hebrew and Korean as well. There are two kinds of syllables, closed and open. A closed syllable ends with a consonant, whereas an open syllable ends with a vowel. Closed syllables have short vowels, open syllables have long vowels. Therefore one doubles the final consonant in order to "protect" a short vowel. Fuse --> fuses, and bus --> busses, according to this rule. The application is entirely phonetic, and does not require knowledge of a lexicon to be applied. Thus the first statement of the Spelling Society contradicts the later statement--because shorter spellings are no longer phonetic.

In fact, "if two spellings are possible, choose the shorter form of the spelling" is a recursive statement, because it suggests that this rule is not being applied if there is a shorter version. Nor can it be applied consistently because then there will be no second spelling option.

So instead of going by the sound and the syntax of the root word, we are now dependent on a dictionary to figure out the right spelling. This is like going back from phonetic spelling to Chinese characters, or like going from the Phoenician alphabet to the Egyptian hieroglyphics. This undoes 3000 years of convention, and you call this progress?

What if tomorrow someone decides to convert a verb to a noun, "Them cops were 'busing me, man." When do we go back and change the spelling of the noun converted to a verb "Bussing"?

Soon it will require an educated elite, possessing the latest in Microsoft software to tell us peons how to spell. Sort of the way hieroglyphics died out with the last Egyptian priest in 300 AD. Bad spellers will be ostracized, discriminated against, prejudiced. I had a friend tell me that my double consonant on "biassing" was going to get my resume rejected!

And fear will drive us all toward buying Microsoft products to check our spelling. Which, of course, will change arbitrarily as they "improve" the spelling the way the spelling society dictates. This will necessitate buying the latest in Microsoft software, lest we be discovered to be using last year's spelling. Like Winston Smith in 1984, we will spend our lives editing more and more dictionaries for Microsoft, because he who controls the language, controls the people.

Stop! Spellers of the world, unite! Discard your Microsoft Word and your Merriam-Webster dictionaries, you have nothing to lose but your chains!

The Nobel Prize in Chemistry is that!

If the Physics Nobel went for a metaphysical theory weakly supported by data, the Chemistry Nobel went for strongly supported data that undermined a bad metaphysical theory. The two prizes could not have been more different than night and day.

First let's try to understand the metaphysics that underpins chemistry, and its subtle message about materialist reductionism. (I'm a physicist, so I'm bound to get the nuance wrong since I don't work in a chemistry, but I had organic chem in college and a course on solid state physics taught by a crystallographer in grad school, and since the topic of the Nobel is crystallography, I thought at least I'd get the physics right.) Let's start with the history.

Now as the Medieval synthesis of Aristotle and Aquinas began to crumble in the Renaissance, the Greek atomism of Democritus and Epicurus began to gain a hearing. Long before physicists would believe in the metaphysical atom (which being unobservable remained a ideal, not a datum), the chemists were finding that chemical reactions had specific amounts: two parts hydrogen plus one part oxygen = water. Whether or not atoms existed, chemistry was most easily explained as the reaction of individual atoms. Later on, physicists found that the gas laws of Charles and Boyle could be best explained by atoms, Maxwell even found velocity distributions for these atoms, and Boltzmann demonstrated that statistics on these atoms could explain all of thermodynamics.

The metaphysics was clear--all of life was reducible to smaller units so that the macroscopic behavior was merely the accumulation of microscopic behavior. Once atoms were recognized, then all the ways to arrange them were tabulated into 7 crystal systems of 32 point groups. Now when you picked up a rock you had never seen before, you could classify it with the exhaustive classification scheme because you knew it was made of atoms. The power in this knowledge was the power of atomism, of reductionism, of a correct metaphysical view of reality. Later on when glass was found not to be crystalline, one made a special exemption for "amorphous" or "glassy" solids that, we were told, were just extremely viscous liquids. But the difference between the categories was clear, crystals had order, liquids did not.

Now this introduces a very old chestnut into the intelligent design community. Since a crystal had order, but was not designed, how does one distinguish between that and the real ID? The answer came back that the order was not very informative. The NaClNaClNaCl repitition in a salt crystal didn't have much complexity. In fact, we could compress the formula easily (NaCl)_n where n is the number of times we need to repeat. This led to the idea of Kolmogorov Complexity, which is the length of the formula or algorithm necessary to duplicate the object. Obviously a crystal could be compressed to a very short string, as we did above.

Well then, what about glass? If we can't crystallize it or compress it to a formula, then does it have more information than salt? In this case we say that it is highly disordered. No two samples of glass will have atoms in exactly the same place, only the average composition can be known. For example, when we send neutrons or x-rays diffracting through glass, they don't form the patterns that crystals form, they don't have strongly peaked Fourier components of a periodic structure. Imagine that atoms were an orchestra, then crystals would be Mozart and glass would be Bartok. That's what these diffraction experiments revealed, that glass had no long range order. It had no information.

In contrast to this inorganic chemistry, living biology was far harder to characterize. For one thing, many organic molecules just resisted crystallization the way honey stays liquid in your pantry. But it obviously wasn't random either. Was there any way that living things could occupy a space between liquids and crystals, being full of information yet not compressed to simple algorithms? The biologists were happy to give information to their enzymes, but the chemists weren't too sure. Everything orderly comes down to those 7 crystal systems, they would say, and there's less information in a liquid than in a crystal. So don't you go trying to explain life as an information rich crystal. (Cue to Dawkins Ruse claiming life began on the backs of crystals.)

In contrast to this reductionist approach to atoms, mathematicians were already exploring systems that didn't fit those 7 crystal systems. The one I recall most vividly was Roger Penrose's tiles that could make 5-fold "flower" crystals but had no repeating units. That is, none of those 7 crystal systems could have 5-fold symmetry, as any crystallographer would explain, because you just can't find a way to tile a surface with pentagons. Hexagons, squares, triangles, yes, pentagons, no. But Penrose tiles do make lovely 5-fold stars and flowers, but without any repeating units. Why is that?

The chemists were adamant. Whatever Penrose does with his tiles, is not possible with atoms.

Well, why not? Aren't tiles made out of atoms after all?

Because such a system would have no repeating pattern, yet still have an overall pattern. It would have long-range order without short-range order. And if we allow those kinds of objects into our world, then humans would not be reducible to interactions of atoms, but would have long-range order that perhaps made them respond to thoughts and emotions and objects on the other side of the universe. That was what Aristotle and Aquinas were promoting! Remember the 4 elements? The reason rocks sink in water is that they are "seeking their own kind" and the reason fire rises in air is it too is "seeking its kind" meaning the sun and the aurora. It was this sort of "spooky-action-at-distance" that assigned purpose and intent and function to inanimate things like rocks and fire that was precisely what the atomist theory was meant to eliminate. Read Lucretius on the need to reduce everything to atoms to remove any affect of the gods on earthly phenomena.

Not only did everything have to reduce to atoms, but all the interactions had to reduce to collisions between atoms. It doesn't get any more local than that. We have doodles of Descartes' trying to show that the planets move, not because they were set in motion like Aristotle, but because little whirlpools of atoms filling the heavens were colliding with them and pushing them along.

Of course gravity didn't fit that model. It really was spooky-action-at-a-distance, but Newton pled the fifth, "hypotheses non fingo" he said and refused to elaborate. And then Faraday started spouting off about electric and magnetic fields, but fortunately theoretical physicists tamed all these spooky things by claiming they are mediated by particles. Sorry, I got carried away with the physics again.

So in a nutshell, the atomic theory of matter is strongly coupled with the local force interaction theory of matter. If we allow atoms to possess long-range forces, then it would appear we are allowing Aristotle and Aquinas a foothold. In biology, this comes down to a Darwinist theory that will not allow organisms to forsee the future and plan their reproduction accordingly. Just as there can be no planning in Darwinism, there can be no global or long-range interactions in chemistry. That was the metaphysical requirement, and the barrier that separated chemistry from biology. Biology is all about apparent purpose, chemistry is all about local reactions, local equilibria that have no purpose.

Then along comes Shechtman. And he had no commitment to the metaphysics of materialism. If long-range order exists and he finds it, he is going to report it. And if five-fold symmetry is observed, then it will be evidence for the long-range order, since there is no way to include it in the 7 crystal systems. He published that paper in 1984 and you would have thought he had reported being abducted by aliens.

The doorkeepers of the journals, the guardians of the metaphysics were not going to allow such heresy. Twenty-seven long years later, we find who won that battle.

But what exactly does it mean that interactions are non-local? It means that quantum mechanics is closer to reality than Democritus' atoms. It means that people are not merely made up of atoms, but atoms carefully arranged by some external force. It means that experiments are not isolated from the universe, but always under the influence of things far away. It means that integer dimensions do not capture reality, but we live in fractional spaces, in fractal geometries that have information at all scales from the galaxy down to the subatomic nucleus. It means that no man is an island, no man stands alone. If ever there was a rebuttal of materialism, if ever there were a way to convince a Darwinist that he can never recover the reductionist purposeless of Darwin, it would be this Nobel prize.

How does this Nobel impact on ID?

It hardly says that crystals are now an intelligently designed inanimate object, but it does say that the geometry of space is intelligently designed. Rather than elevating crystals to the level of consciousness, it demonstrates the incompleteness, the utter poverty of space and time in which materialism disrespects the geometry of nature. Rather than a Maginot Line between information rich Biology and information poor Chemistry, there is now an entire world, an infinite spectrum of places to tuck in information. Today we are reading the message in the genome, tomorrow we will be reading the message in the quasi-crystals.

We truly live in the Information Age.

A Nobel Prize in Physics for what?

I don't know whether to laugh or cry. Everyone expects the Nobel Peace prize to be a joke. For one thing, the Norwegians who select it are elected officials,I mean what else would you expect from a professional politician? But the Nobel prize in Physics is awarded by the Swedes. It is supposed to be for lifetime achievement, which explains why the Medicine Nobel was given to a fellow who up and died two days before. (No, they aren't taking it back from his widow.) So you would think the Physics prize would go to a whitehaired professor with baggy trousers and leather elbow patches on his jacket. I mean a whole pile of previous Nobel prize winners vote on it!

Oh. I see what you mean. I suppose that is a weak point too. Positive feedback can be quite devastating. Well, maybe that is what afflicted this year's choice. But I suspect worse. Well, what was the award for?

It went to three astronomers for carefully measuring the light from distant supernovae--fifty of them to be precise.

Okay, you are asking, what makes this discovery special? If we examine the Nobel citations, we see that novel discoveries, building a better instrument, and sometimes bold theories that transform the field are the major reasons for awarding the Nobel. Since the Nobel is not supposed to be awarded to dead people, sometimes a worthy recipient is cited for "lifetime achievement" just before he dies. Hence the trio of ancient physicists that got the prize in 2009. So which category does this year's prize fall into?

Have supernovae been observed before? Oh sure, all the way back to the Chinese astronomers in 1054. Some would even say that the Christmas star was a supernova. How about 50, is that a special number? Not really, the era of robotic telescopic observations permit thousands of such objects to be observed simultaneously from both ground and space-based telescopes 24/7. So if it wasn't the observation that was so special, was it the technique? Nope, they used other peoples instruments and data sets. So if it isn't the observation and the technique, is it lifetime achievement? Absolutely not, these are rather youngish astronomers.

I carefully tabulated the last 110 years worth of Nobel prizes and this is the chart I got for the ages.

The trend has been toward older and older Nobel prize-winners, with a trend line of one decade per 50 years. Right before the last 2 years, the average age was above 60. The overall average is 54 years old. This years winners averaged 46 years old, last year 44, and the year before that 80! So we see that the Nobel committee must think either that they need to award younger men (only two have been women), or perhaps these men are above average in contribution. Or is it something else?

We've eliminated novel observations, novel techniques, lifetime achievements, which leaves only bold theories that change the paradigm. What theory did these 50 supernovae prove?

Dark energy.

What's that? Well, to be more precise we could called it negative pressure, or perhaps anti-gravity. But it acquired the name "dark energy" to make it sound like the other thing nobody can explain, which is "dark matter". Now matter that is dark is hard to see with a telescope, especially when it is far away. Sometimes we can see it when it obscures the light from behind, as in dark nebula. But many times it doesn't even do that, and we only discover it by its gravitational affect on the "bright matter" around it. So the name is self-explanatory. But what does "dark energy" mean?

The story goes back to Einstein, who was a materialist and therefore like the Greeks before him, wanted the world to have no beginning, because without a creation there need be no creator. Unfortunately, gravity pulls everything in, so if the universe was eternal, something had to balance out the gravity that was trying to pull it in. Newton accomplished this with a careful balancing act--putting as much matter outside as inside in order to pull it in both directions at once. Einstein's equations, however, had nothing on the outside, but gravity warped the space with no way to flatten it back out. After staring at his equations, Einstein decided that his metaphysics required a modification, and he added in something called "The Cosmological Constant" to balance the gravity. This is the exact same item that today has been called "dark energy". Later when Hubble observed the galaxies all rushing away from each other, Einstein realized that an explosion would neatly keep the galaxies apart, and he removed the constant, calling it "his greatest mistake."

Therefore this constant has been in disrepute since the 1961 discovery of the "Cosmic Microwave Background Radiation," which is the observation of the light emitted 13.7 billion years ago in that enormous explosion. It also generated 2 Nobel prizes for the discoverers, Penzias and Wilson. Robert Jastrow wrote about the effect this observation had on the astronomy community in his 1978 book "God and the Astronomers". The last 3 sentences of his book get quoted a lot, but it bears repeating:
At this moment it seems as though science will never be able to raise the curtain on the mystery of creation. For the scientist who has lived by his faith in the power of reason, the story ends like a bad dream. He has scaled the mountains of ignorance; he is about to conquer the highest peak; as he pulls himself over the final rock, he is greated by a band of theologians who have been sitting there for centuries.
This has been infuriating for materialists who would give their eyeteeth to be able to get rid of the creation with its implied creator, and go back to the eternality of Democritus. Sir Fred Hoyle, a self-professed atheist and follower of Democritus, denied the reality of the creation, which he attempted to ridicule as "the Big Bang". Despite his enormous intellect, he was unable to persuade very many astronomers of his position. There have been many attempts to make the Big Bang cyclic, and thereby eternal, but one of Stephen Hawking's first contributions with Roger Penrose was to show that this didn't work. \ Roger Penrose a member of the atheistic Humanist Society, however, has attempted a different kind of cyclic Big Bang which resulted in a bizarre publication last year. Hawking, another self-professed atheist, tried to get rid of the Big Bang, first by making time imaginary in his "A Brief History of Time", and now by invoking another 7 dimensions of reality in "The Grand Design".

All of these proposals have been attempts to metaphysically remove the Big Bang. I call them metaphysical, because their central premise is that reality is not the way it appears. Hoyle had protons appearing miraculously out of the vacuum and light getting tired as it got older. Hawking first had to make time an imaginary quantity, now he wants to invoke 7 more imaginary dimensions. Penrose wants so much time that spacetime loses track of its size.

These are not idiots. In fact, if you read the literature of their atheist clubs, they value Reason over all other attributes of man. It is because of their Reason that they consider themselves atheists. Yet their worship of Reason has made them adopt unreasonable positions. We are talking serious physicists here who have abandoned physics for metaphysical statements that in principle cannot be measured.

So when three rather youngish astronomers say, "Look at that, these supernova are dimmer than we expected, could this be evidence of dark energy? Could this be proof that maybe the Big Bang wasn't necessarily the beginning?" You can just imagine the electric jolt that went through the materialist community.

For the first time since Einstein's greatest blunder and since Penzias' and Wilson's discovery, there was data for Democritus and materialism. Now let's be clear, the "dark energy" cabal isn't yet ready to dismiss the Big Bang, but they are well on track for finding solutions to Einstein's equations that make it less and less necessary. First we demonstrate anti-gravity, next we start finding proof of "inflation" and "baby universes" and the "multiverse" is just around the corner.

What exactly is "dark energy"? Nobody knows. It is invisible. It has no effects on any experiment you can do in the lab. It is only quantifiable in the sense that computer simulations that attempt to distribute galaxies in the universe use it as a dial on their codes. When the dial is set at "11," as Spinal Tap would remind us, then we get a better fit. It's physical reality is right up there with the positive feedback parameter in global warming climate codes. It has only a "virtual" reality.

What about this supernovae data, isn't that a slam dunk for the existence of dark energy? (just look how far those data points are from the expected straight line!)

Actually no. Just last week a sixth theory to explain the supernova data without dark energy was announced. For reference, here are a few of the "normal science" explanations that can account for the data.
1. Perhaps the stellar codes (derived from LosAlamos bomb codes) that calculate the light output are in error, just as the were wrong about the mixing ratios in the center of our own sun, so that there is a size-dependence and light-dependence to these supernova.
2. Perhaps far away supernova are dimmed by dust, plasma, light interactions, scattering, etc. The reason they look dimmer the farther they are away, is that there is more and more dust between us. (The z-scale used for x-axis is nearly logarithmic, compressing distances.)
3. Since far away supernova went off earlier in the history of the universe. Perhaps the composition of the star that exploded back then was different from nearby supernovae--specifically, the metallicity--making the light output depend on composition.
4. Since far away supernova went off earlier in the history of the universe. Perhaps the physical constants back then were slightly different than they are today, changing the light output.
5. Perhaps they really are further away because our galaxy is in a less-dense region of the universe, and like a bubble in champagne, it is expanding locally, making it appear as if it is accelerating faster than it should.
6. Perhaps our galaxy and the some of the ones near it are flowing in a "dark flow" through the universe, making supernova in some directions dimmer, while in other directions they look brighter.

The nice thing about most of these alternative explanations, is that they don't invoke any unobservable metaphysical substances like "dark energy". Wouldn't that make them more scientific than dark energy, and not less? Wouldn't the Nobel committee wait for slightly better confirmation of "dark energy" before they award the prize? Like some other measuring stick than supernovae? Why are they so hasty?

Well, other than trying to improve their age statistics that we noted in the graph above, another reason for haste might be economic. NASA has been studying a "Joint Dark Energy Mission" for nearly a decade. This year the New York Times published an article how this mission wasn't faring too well in the constrained budgets of this administration. We're talking a $1.6 billion initiative, which if it overruns the budget like the James Webb telescope, may be multi-billions of funding to the astronomy community. The NYT even quotes the future Nobel winner, Perlmutter, saying he doesn't think this mission will go forward. Of course, if it is now considered Nobel-prize-winning science, maybe NASA will have a change of heart. Maybe this is a proactive Nobel, awarded for spurring future research rather than past. Sort of like the Nobel Peace prize in 2009.

God save us all.

Hell is Payback


Perhaps you have seen the PETA billboard that went up after a boy was bitten by a shark while spear-fishing. PETA thought they could capitalize on this shock value of this by inserting their none-too-subtle message on a billboard. But whatever the merits of such tacky exploitation of human tragedy, the part that got me was the subtle pantheist religious sentiments of both the billboard and the execrable defense that PETA provided for their insensitivity to the boy and his family. So this is my billboard.

Hell is Payback.

Just how many monkeys = Shakespeare?

A recent blogger has announced that a few million simulated monkeys really could reproduce Shakespeare. This is such a hoary chestnut, that of course, everyone had to go and read just exactly what the fellow actually did, if only to ridicule it. Here's how he describes his project,
Instead of having real monkeys typing on keyboards, I have virtual, computerized monkeys that output random gibberish. This is supposed to mimic a monkey randomly mashing the keys on a keyboard. The computer program I wrote compares that monkey’s gibberish to every work of Shakespeare to see if it actually matches a small portion of what Shakespeare wrote...
For this project, I used Hadoop, Amazon EC2, and Ubuntu Linux.  Since I don’t have real monkeys, I have to create fake Amazonian Map Monkeys.  The Map Monkeys create random data in ASCII between a and z.  It uses Sean Luke’s Mersenne Twister to make sure I have fast, random, well behaved monkeys.  Once the monkey’s output is mapped, it is passed to the reducer which runs the characters through a Bloom Field membership test.  If the monkey output passes the membership test, the Shakespearean works are checked using a string comparison.  If that passes, a genius monkey has written 9 characters of Shakespeare.  The source material is all of Shakespeare’s works as taken from Project Gutenberg.
The bit about well-behaved monkeys is necessary, because the actual experiment reported,
In 2003, scientists at Paignton Zoo and the University of Plymouth, in Devon in England reported that they had left a computer keyboard in the enclosure of six Sulawesi Crested Macaques for a month; not only did the monkeys produce nothing but five pages consisting largely of the letter S, (the full text may be found here:), they started by attacking the keyboard with a stone, and continued by urinating and defecating on it.
Which would be my reaction too, if at two years old I had been given a toy that was tactilely boring, visually structured for no apparent reason, acoustically monotone, hopelessly inedible and smelled like old coffee. But people aren't as rational as monkeys, and so they spend hours with that thing, banging on it interminably, writing parables about monkeys on keyboards when everyone knows it is really about people. But is it true that a genius monkey could type nine letters of Shakespeare?

Well, of course, but fitting those 9 letter fragments back into a jigsaw puzzle of Shakespeare takes a bona fide human. As one blogger put it, this is just Dawkin's Weasel program all over again--comparing a partially completed solution to the final solution, and modifying only the parts that are wrong. Not a very random way of using those monkeys at all! Imagine taking an MedCat exam where the professor told you which multiple choice problems were wrong and to go back and change them. Even without knowing anything, how long would it take you to score a 100%?

But what would it take to get Shakespeare without any human intervention at all? How long long would it take to collect, say, a page of Shakespeare, say 500 words or 2500 letters completely randomly?

I wouldn't hold my breath for the genius monkeys. This one has been around for a long, long time. From the 2003 internet we can find the software for running it on our own computer. And the blog forums report the progress (cached versions from original site that went down 7 years ago). This comment from Evan Kirschbaum at HP Laboratories:
That seems about right. I'm getting 6 characters about every four or five seconds and there appear to be about 70 characters in the set, so a back of the envelope calculation shows that you should get 7 letters after about 5 minutes, 8 letters after about 6 hours, and 9 letters after about 18 days. (And as I was typing that, I got my first seven letter match: "1. When" from the beginning of Macbeth .) Ten letters would take about three and a half years, and you won't live to see eleven letters (239 years). If a million of us work on this, it'll take two hours to get eleven letters, 14 months to get thirteen, and 82 years to get fourteen. (Got my second seven letter match: "DukeE." from Measure for Measure .)
Okay, how does this work? I'm not sure how Evan justified his calculation, but it seems he was working with the "doubling time", how long does it take to get one more letter is proportionally constant. So he's assuming the ratio Time-for-6-letters / Time-for-5-letters = Time-7 / Time-6.  Let's see how that works out.  His 6-letters is 4.5 sec; 7-letters is 300s (= 5 min);  8-letters is 21600s (= 6 hr); 9-letters is 1555200s (=18 days). Then taking ratios we have 7letter/6letter = 66; 8lett/7lett=72; 9lett/8lett=72; So it looks like his doubling ratio was about 72.

Why ~72? Because he assumed that each letter was drawn from a set of 70 characters, so the information per letter was 70= 26.1 or 6.1 bits. Therefore adding a letter required 6 doublings, or a factor slightly more than 64. But did each letter really add that much information?

Claude Shannon, the inventor of Information Theory, addressed this same problem in one of his little papers that shook the world. He asked a related question: If I erase every other letter (or more) can people reconstruct the sentence? By doing this, he was able to figure out how much information was encoded in the first letter, the 2nd letter and so forth. The answer is that the first letter has some 4 or so bits of information decreasing smoothly to about 1.7 bits of information by the time you reach the 10th letter. You can check that out with this web applet.

Then the probabilities are easy to calculate--just add up the bits. Not having his paper in front of me, let me just pretend it is the sequence 4 + 3 + 3 + 3 + 3 +2 +2 + 2 + 2 = 24 bits in 9 letters. Then 1 in 2^24 are the number of equivalent bits of information in the string, which is 1.68 x 10^7 tries, or 16 million tests. If his circa 2002 computer operates at 100 MHz, and does a thousand comparisons per second, then 16 million tests is completed in 160 seconds or about 3 minutes.

Why the difference?

Well, for one thing, Kirschenbaum was calculating the information from a 70 character alphabet, and Shannon reduced it to 27. Already that is a difference of 6.2 bits versus 4.7 bits. But more importantly, Shannon is asking how much information English speakers assign to each letter, which is a lot less than what the computer assigns to each letter. That's just another way of saying that English text can be compressed by at least a factor of 2. That is, 26 letters of the alphabet plus a space (using only caps) is roughly 4.75 bits of information, but real speakers of English find only 1.7 bits of information after the first few letters. That's because English readers know the rules about words starting with X, and a U after a Q, etc. All those rules mean that the next letter is not really 1 in 27, but more like 1 in 3. So a decent compression algorithm should be able to squeeze English down by 1.7/4.7= 35%.

Back to our Million Monkeys algorithm. When it converts all of Shakespeare into 9-character strings to make the comparison with the randomly generated strings, how many strings is that? The Shakespeare corpus has 884,647 words, which are probably a tad over 5 letters each, for about 4.8 million letters. So does that mean there are approximately 4.8 million 9-letter strings we can extract from his works? No, because those 4.8 million character strings from Shakespeare are all restricted by the rules of English, and so many of them will be identical. Using Shannon's method of calculating above we will have about 224 possible strings, or only 16 million potential strings. This is larger than Shakespeare's corpus, so perhaps the duplicates aren't so big a problem. Let's say this reduces Shakespeare to 3 million unique character strings. Then the calculation using Shannon's method (27 characters = 26 capitals and a space), we get the following statistics:

5 letters = 275 / 3 million = 4.78
6 letters = 276 / 3 million = 129
7 letters = 277 / 3 million = 3500
8 letters = 278 / 3 million = 94,000
9 letters = 279 / 3 million = 2,500,000

Notice that the comparison to Shakespeare's corpus is a constant that cancels out when ratios are taken. This is what makes Kirschenbaum's method work. But if 6 letters took 5 seconds for Kirschenbaum, 7 letters ought to have taken 2.5 minutes. Since Kirschenbaum saw two 7-letter options spring up while he was typing that text, it suggests that his factor 72 was too large, and he should have been using something a bit smaller, maybe closer to Shannon's 27.

So to answer our question about achieving a page of Shakespeare of 2500 letters, we can now calculate that:
272500 / 3 million = 8.5 x 103571 which is longer than the age of the universe by a long shot. If we want Shakespeare any time soon, we'll have to hire some of Dawkin's weasels.

Einstein, neutrinos and time travel

The bartender says, "We don't serve neutrinos here"

A neutrino walks into a bar.

The blogosphere is all abuzz about the CERN neutrino experiment that reported "faster than light" travel for the neutrinos. We all heard the news first from the blogs, and now the arXive pre-print server has the details. This immediate publication is already truly amazing, given the months before the paper copy appears in the library journal. The comments and consequences are flying so thick and fast, one hardly has time to absorb the impact. Einstein published his Special Theory of Relativity some 107 years ago, and this has been the first, contradictory laboratory evidence for "superluminal" transport.

But already, one day later, the first theorist has chimed in with an explanation. Not to miss any opportunities, the same theorist has a second explanation, with a different cast of secondary authors. Since both papers are written exclusively by Italians, it would appear that they had their theories ready to go as soon as the experimentalists were confident enough to publish. Other theorists weren't so fortunate to get advance notice, but they are quick with their theories too. Frank Close, an Oxford physicist who just published a book on the Neutrino, doesn't think his life's work was wasted quite yet.
 "Has Cern overthrown this paradigm? I doubt it. Light travels slower through water, glass, even air, than through a vacuum. Radio waves do, too. So light can be slowed down, but not sped up: the vacuum is nature's open road where light travels at the speed limit. We need to be careful when asking what exactly has the Cern experiment done, or, more pertinently, how did it do it?"
Looks like he hasn't read the arXive paper where they explain carefully how they did it, perhaps because his response like mine preceded the publication. Every physicists first question was--how can you measure +/- 10cm over 730km, GPS isn't that accurate! The article explains: with great difficulty. But apparently no expense was spared to get a geodesy model to measure the distance within 10 cm. Atomic clocks were carried into the tunnels to calibrate the timing. Lasers were used to measure the distances down the tunnels. A commercial firm was hired to produce an independent model. Earthquakes and continental drift were used to calibrate their model. If they did make a mistake, it won't be just scientist's reputations lost, there will probably be lawsuits too.

Let us first dispell the misconception of scientists clocking individual neutrinos starting at the Franco-Swiss border and arriving in Italy. No one can see an individual neutrino twice. In fact, you have about 100 million neutrinos from the Sun going through you each second and you don't even notice because their interactions are so very rare. Neutrinos can go through the entire Earth without much chance of interacting. That's why the neutrinos have to be detected statistically. Imagine a marathon that is so crowded that every 20 minutes, another 100 runners were allowed to start, and each runner's time was determined by subtracting off the start time. This is how the neutrinos were produced, in 10.7 microsecond long bunches, separated by 50 microseconds. Unlike a marathon, however, the experimenters assumed that every runner runs exactly the same speed, so the bunch at the end of the race should look just like the bunch at the start gate. Then by aligning the stop bunch with the start bunch will give the time of flight. The paper shows how the alignment looks if they use the speed of light, and how much better it looks if they use a very slightly faster speed. The difference is 60 nanoseconds, which when multiplied by the speed of light of 1 foot per nanosecond, gives 60 feet.

Is this within the error of their distance measurement?

This is the crux of the experiment. Over in Chicago, the scientists at Fermilab had done a similar experiment and likewise had found that neutrinos possibly travelled faster than the speed of light. But the Fermilab scientists didn't want to go through so much expense as the Italians and so they said "we probably made an error, since our uncertainties are bigger than the difference." That is why the Italians spared no expense to get their uncertainties as small as possible. And they got the same result as Fermilab, but this time the uncertainties were 1/6 of the offset, or a "six sigma" result. In experimental science, six sigmas is as close to certainty as you can ever wish for.

So let us assume that both the timing and the distance have been measured about as well as modern technology allows. How then does one explain the effect?

Well the measurement is a statistical measurement of a subatomic particle, which means it is a Quantum Mechanics measurement, and when it comes to QM, statistics are not what they first appear. For example, if you put one foot in ice water, and another in boiling water, you might statistically feel fine, but not in reality. Likewise, statistically the neutrinos might be going faster than light, but individually and in reality none of them are. For example, suppose that only the leading edge of the 10.7 microsecond pulse creates interactions, but the shape looks like the trailing edge of the protons, so that matching shapes gives a false impression of faster-than-light travel.

A second issue is that the neutrino is describable by a wave-function in QM, which is not a single point but spread out over a region of space. One usually describes the wavefunction in terms of a "wave packet" that looks something like an American football, tapering to a point at the front and back. The speed of the football is the "group velocity" and this is the object that has to travel slower than the speed of light. But the interior of this football is full of waves, and those waves can move faster than the speed of light, which is called the "phase velocity". It is the phase velocity that gives the packet its interior shape, though it is the center-of-packet that gives the group velocity. Now the Italians are correlating to the shape of the packet, and if this means they are statistically sensitive to the phase-velocity, they may be fooling themselves thinking they are measuring simply the group velocity.

A third issue is related to the one above. If a wave-packet has a width, then a measurement of the leading edge of the packet and subtracting off the tail-edge of the packet will cause an offset of approximately the width of the packet. That is, when the proton makes the meson that decays into the neutrino, we time the proton and assume that the neutrino acts as if it were collocated with the proton. But perhaps the neutrino acts as a wave that is not collocated with the proton. It would be quite unusual for the wave packet to be 20 meters long, but perhaps it is QM entangled pairs of particles that have this length. Supposing that this entanglement is somehow energy related might account for the fact that MeV neutrinos don't seem to have anomalous offsets, 15GeV neutrinos have a 53ns offset, and 40 GeV neutrinos have a 67 ns offset.  

Having discarded all explanations that rely on errors in timing or distance, we are left with QM wave-particle effects which are not well developed for neutrinos. The closest cousin to a neutrino is an electron, and it weighs in at 511,000 eV/c^2, whereas these neutrinos are thought to weigh much much less, some putting this particular muon neutrino at a rest mass of only 0.003 eV/c^2. This means that the wavepacket size is almost entirely defined by its kinetic energy, which at GeV energies should be sub-atomic length, which is how it interacts with matter--through the weak force at the subatomic level. But no one is really sure, since it is quite difficult to do experiments on such slippery particles.

Let's play a few games with equations, and see what happens. Suppose the rest mass of the muon neutrino is 0.003eV/c^2 (as determined from flavor oscilations between 1 & 2). Then 40GeV/0.003eV = γ = 1.3 x 1013. Now events that happen in the rest frame of the neutrino will be multiplied by gamma in the experiment frame, so things that go quickly in the rest frame will appear to go very slowly in the experiment frame (e.g., the decay of muons from air showers). So let us estimate how long a virtual neutrino-antineutrino pair will last in the rest frame. From Heisenberg's Uncertainty, ΔE x Δt = h, or, 2(0.003eV) Δt = 4x10-15eV-sec ==> 6x10-13 sec. Now we multiply that by γ to get the experimenter's viewpoint, and find γΔt = Δt' = 8 seconds. Well it only takes 2 ms to go the 730 km from Switzerland to Italy, so in some bizarre fashion, the experiment in Italy is coherently coupled to Switzerland, and we should be using QM correlated statistics rather than uncorrelated statistics.

This experiment was first performed at Fermilab over about the same range, and the 2007 paper reported a speed just a tad slower than the speed-of-light for 3 GeV muon neutrinos. Unfortunately the dither in their GPS contributed 120ns error, and they could only say that the error bars included a possibility of faster-than-light travel as well.  The smallest error bars are for the Supernova 1987A neutrino detection, which found the speed of the 10 MeV electron neutrinos to be very very close to the speed of light. Not only does the smaller gamma for these supernova neutrinos shorten the correlation length, but the astronomical distances should uncorrelate the wavepackets as well. So on the surface, I would suggest that the mystery can be solved through proper attention to QM effects.

Does this result invalidate Einstein?

Not yet. But it does show the difficulty of making Einstein's relativity consistent with quantum mechanics. Einstein apparently despised QM as being "incomplete" so he didn't care about agreement, but the past 60 years have been spent trying to construct a unified theory. And while the weak force (which controls neutrinos) was thought to be well incorporated with photons/electrons into an "electroweak" theory, the discovery of the Higgs boson that was supposed to confirm the theory has proved elusive. So perhaps there remain mysteries in the electroweak formulation, mysteries compounded with these neutrino results.

No.

What about time travel?

Astrobiology, Hawking, and The Importance of Being Info

I have returned from the annual non-NASA Astrobiology conference, which I attended this year and delivered two papers. After my NASA colleague's long-delayed paper on the discovery of microfossils in carbonaceous chondrites (meteorites that are widely believed to be extinct comet fragments) was accidentally published in March when Fox News broke the paper embargo that led to 40 million web hits, I had fond hopes that this would be the conference that broke the ice about ET. In fact, my first paper was entitled "More Evidence for Liquid Water on Comets" which recorded the mounting evidence that indeed, comets are natural bio-transporters for moving biology all over the cosmos--sorta like Arthur C. Clarke's novel "Rendezvous with Rama".

Curiously, NASA has been having press conference frenzy about, you guessed it, liquid water again. First there was evidence of past water, then present water found on Mars, then briny liquid water, and soon to be fresh liquid water. Maybe, like the LCROSS impact on the Moon, it will now become swimming pools of fresh water. If you recall, the reason given in 1976 for rejecting the evidence for life in Gil Levin's "Labelled Release" experiment on the Viking Mars lander was because "everyone knows Mars is dry as a bone." So perhaps Hoover's paper is having the desired effect: water and gold are exchanging places in the solar system, from rarity to commodity. (If only Levin's experiment had detected gold we'd be back there already . . . )

But the second paper was far more challenging to write. It was an answer to Stephen Hawking's inspired nonsense about M-theory. You can read mathematician Lennox's critique (here's a review of Lennox's book) but what you won't get from him is any idea why Hawking, the atavar of British reserve in his 1986 best-seller "A Brief History of Time", had become a foam-flecked mouthpiece of new atheism. The answer was that the mathematics of his specialty--the Big Bang Cosmology--was becoming untenable, and evidently it was driving him to distraction. This is just another microcosmic example reflecting the fact that the paradigm worldview of the 20th century, the idol which reigned supreme from the publishing of Darwin's "Origin of the Species" through two World Wars and the raising of the Iron Curtain was now crumbling as certainly as the Berlin Wall. (Which, in fact, was the thematic background for Ben Stein's "Expelled" documentary about Darwinist dogmatism.)

Everywhere you look, the Modernist juggernaut is stalled and smoking. If it isn't too big a stretch, the failure of governments in Tunisia, Libya, Egypt and Syria, the failure of the Euro-zone, the failure of NASA to launch astronauts, are all emblematic of the failure of Modernism to thrive in the 21st century. The progressive utopia of New Deals, New World Orders, and New Frontiers has retreated into the mists, taking its promises and its promoters into the swamp with it. Even that Modernist paragon of critical skepticism, the man who dominated the philosophy of atheism in Britain representing the pinnacle of enlightened thought, Anthony Flew, recanted his atheism in 2004. It has been a bad beginning to a new century, a new millennium, and Hawking, like most brilliant men, is very aware of this failure of his life's goal, of the purpose of his career, of his cultural worldview, and it is driving him mad.

Now the death of Modernism has been a long time coming, and it would be fruitless to try and pin a date for its last breath. But more importantly, we need to ask the question, what comes after Modernism?

And that is what Hawking is aiming to provide.

The explanation requires that we make A Brief History of Hawking. The history of Modernism is intertwined with the history of materialism. For as the atomic theory of matter gained credence throughout the 19th century, the organic theory of matter, the purposeful motion of the four elements and the perfection of the heavenly bodies lost credence. As this de-mythologizing of nature continued with Darwin's theory of accidental life (1859), there did not seem to be anything left of life's mystery except the math.

That is, there is no doubt that in the 1930's quantum mechanics undermined the atomic theory of matter, but it did so with a peculiar arithmetic that did not seem to obey the rules of cardinal numbers. One plus one no longer equalled two, and only by arcane math could one discover the secret answer. This triumph of pure unapplied math over nature would later earn Eugene Wigner a Nobel prize in physics, and the tradition continues today with hordes of theoretical physicists pursuing the unapplied mathematics of "string theory" in search of the secret to the universe. Stephen Hawking was one such theoretical physicist, wrestling with the math in his physics papers on cosmology and the properties of the unobservable black hole.

This transition from atoms to black holes is significant for Hawking, because it represents more than his personal journey, but the very birth and senescence of materialism, and by close association, of Modernism as well. The physicist who was hugely influential in Hawkings career and who had coined the moniker "black hole", John Archibald Wheeler, wrote that his career had moved through three phases, from "Everything is particles" to "Everything is fields" to "Everything is information." Wheeler spent his first 20 years during WWII doing nuclear physics whose metaphysical foundation was Newtonian materialism. The next 20 years of his life were spent "recertifying" cosmology and its emphasis on the geometry of spacetime, using a mathematics that superceded Newton. While it was a bit of a shock to lose the solidity of Newton's particles, there was a certain comfort in finding a differential geometry that replaced Newton's gears and cogs with geodesics and light-cones. What Materialism lost in sharp definitions it gained in rococco ornamentation. Hawking, with Wheeler, had made the transition from atoms to math, but unlike him, was not willing to take the final step. What was so formidable about this step?

As Wheeler's biographer Kenneth Ford, recounts,
Enter the "Information Period." Wheeler, in his later years, has been asking two kinds of questions. One centers around the reality of existence "out there" independent of our observations. . .The other kind of question concerns the nature of physical law. "It from bit?" is Wheeler's way of asking if the nature and the behavior of the world around us ("it") is accounted for entirely by on-off gates of information ("bits"). Is the computer a better model for nature than the differential equations of continuous variables that has governed physics for several hundred years?
Here's another popular cosmologist, Paul Davies, explaining Wheeler,

To fully understand nature at the deepest level we need to know why the world obeys quantum rules. Part of the answer involves knowing how the quasi-classical world of observation emerges from the weird domain of quantum physics. Wheeler's "It from bit" program proceeds from a well-known yet still mysterious fact. The wave function describing a quantum particle expresses what is known about that particle, i.e. it represents information, or software, whereas the particle itself is an object, or hardware. How do these fundamentally different concepts, associated with different levels of description, fit together, and how does this fit recover the usual notion of "reality"?

In his own words, Wheeler writes,
It from bit. Otherwise put, every "it" — every particle, every field of force, even the space-time continuum itself — derives its function, its meaning, its very existence entirely — even if in some contexts indirectly — from the apparatus-elicited answers to yes-or-no questions, binary choices, bits. "It from bit" symbolizes the idea that every item of the physical world has at bottom — a very deep bottom, in most instances — an immaterial source and explanation; that which we call reality arises in the last analysis from the posing of yes — no questions and the registering of equipment-evoked responses; in short, that all things physical are information-theoretic in origin and that this is a participatory universe.
That is, Wheeler no longer thinks that materialist particles are the ultimate reality, nor does he think that neoclassical geometry is the ultimate reality, but some strange hybrid that transcends both. For the universe is only poorly described by math, and something more digital, something more quantum-like, something like participation is closer to ultimate reality. He isn't sure what it is, but in his usual style he already has a name for it, Information.

What exactly is this replacement metaphysics, and why does it frighten Hawking so much? Let's begin with some simple observations, moving up to some less-obvious.

1. Information is non-material, so nothing of Plato's or Democritus' eternal atoms remains in the metaphysical foundations of physics. This may have been shocking in 1904 before Einstein told us that matter and energy were the same thing, but we've had a century to absorb this immateriality of reality. Today we glide over this embarassing failure of materialism by saying "of course, the sum of matter and energy is eternal and conserved."

2. But the evidence for the Big Bang would seem to belie this commonly stated aphorism as well. If both matter and energy had a beginning, then there was a time when they were not conserved. Once again, the metaphysical pillar of materialism appeared to crumble. Fred Hoyle attempted to remove the Big Bang entirely so that materialist eternity was preserved, but ultimately failed. Hawking, tellingly, merely attempted to blunt the point of the Big Bang (as recorded by Carl Sagan's introduction to "A Brief History of Time"), but then went on to argue in his most recent book that there has been an infinity of Big Bangs exploding in some eternal mathematical space.  While Hoyle restrained his eternities to observations of this universe, Hawking is having to invoke unobservable multidimensional mathematical eternities.

3. But information is not energy either.  This has taken physicists even longer to accept. To say that the most fundamental nature of reality is neither matter nor energy demolishes this last fiction of eternity, this last pretense that the creation could be finessed. Hawking fought back with the idea that information was merely a state of matter and energy, and that when black holes swallowed information it vanished. Leonard Susskind carried on a 10 year battle with Hawking, finally declaring victory in his book "The Black Hole War: My Battle with Stephen Hawking to Make the World Safe for Quantum Mechanics" when Hawking finally admitted information was eternal.

4. Information, as defined by Claude Shannon, was the opposite of entropy, of disorder, of chance, of random noise. Information not only was immaterial, it was order, plan, design, improbability, an intrinsic value. It was everything that Democritus hated, everything Lucretius warned us against. It was the meaning to the celestial music of the spheres, the joy in the lark's song, the beginning of wisdom and the end of all pursuits. It was Plato's Demiourgos and Aristotle's Prime Mover and Aquinas' Cosmological Proofs.

What was it that made Hawking so terrified of Information? Because Wheeler is saying that the matter and energy of the Big Bang was created but that the Information, the Forms, the plan, the teleology, the logos of that creation was eternal. Hawking like Hoyle and unlike Wheeler and Flew, could not bear to dispense with the whole purpose of materialism--the denial of purpose. Flew, the son of a Methodist preacher and theologian, and Wheeler, the grandson of New Hampshire (Puritan?) pastor could perhaps grudgingly accept this grand design, but neither Hoyle nor Hawking had the benefit of religious ancestors. Materialism was their religion, and the Modernist century was the last great hope for an Enlightenment utopia.

And so Hawking wrote his last long book, like Lucretius, as a paeon to the triumph of man and materialism over the vicissitudes of life and Lou Gehrig's disease. Lennox finds it a hopelessly incoherent denial of theism, and rakes it over the coals of logic. But Hawking never intended it to be a textbook, he wanted a passionate defense of Modernism. And therein lies the rub, for Modernism, like the nirvana of Buddhism, eschews passion in the name of Reason. This makes Hawking's swan song not a defense of Modernism as he intended, but a testimony to Post-Modern authenticity. In such a way we see the Post-Modern replacement for the Modernist century, foreshadowed in the words of Yeats most famous poem--The Second Coming:
 
TURNING and turning in the widening gyre
The falcon cannot hear the falconer;
Things fall apart; the centre cannot hold;
Mere anarchy is loosed upon the world,
The blood-dimmed tide is loosed, and everywhere
The ceremony of innocence is drowned;
The best lack all conviction, while the worst
Are full of passionate intensity.

So it is that the 21st Century has become The Information Age, the killer app of the Enlightenment. As Post-Modernism absorbs the utopian dreams of the 20th century, it tempers them with the knowledge of diversity, of communication, with the great body of individuals united by thought and by internet. A new sort of consensus is arising, not based on monolithic Reason, which is far less hostile to the religion of 19th century. Biology is no longer about thermodynamic equilibrium, it is no longer about non-equilibrium chemicals in a bag, rather it is about nanomachines and programs, about purpose and design. Biology has become Information. It is in this context that I wrote a paper on the Origin of Life as an insoluble information theoretic problem that can be resolved only through the non-local quantum coherence of the universe. I like to imagine that had Wheeler lived to read it, he would have liked it too.

"Romulans" presence suggested by microwave background

the team has located possible 'Romulan presence' in the WMAP data
Scientist has located possible 'Romulans' in the WMAP data.

The idea that it may be possible to penetrate the "Romulan invisibility cloak" has received a boost.

Studies of the low-temperature glow left from the Big Bang suggest that several of these "invisibility cloaks" may have left marks on our sky.

This "Romulan presence" idea is popular in modern physics, but experimental tests have been hard to come by.

The preliminary work, to be published in Unphysical Review D, will be firmed up using data from the Planck telescope.

For now, the team has worked with seven years' worth of data from the Wilkinson Microwave Anisotropy Probe, which measures in minute detail the cosmic microwave background (CMB) - the faint glow left from our Universe's formation.

'Mind-blowing'

The theory that invokes these Romulan cloaks - a theory formally called "warp drive" - holds that as interstellar spacecraft pop into and out of the galaxy using this method, they leave telltale effects on spacetime.

Hiranya Peerless, a cosmologist at University College London, and her colleagues have now worked out that when a spacecraft pinches off spacetime in its warp drive, which is very similar to the process that makes baby universes only smaller, it may leave a characteristic pattern in the CMB.

I'd heard about this 'warp drive' for years and years, and I never took it seriously because I thought it's not testable," Dr Peerless told BBC News. "I was just amazed by the idea that you can test for the presence of all these other spacecraft out there - it's just mind-blowing."

Dr Peerless' team first proposed these disc-shaped signatures in the CMB in a paper published in Unphysical Review Letters, and the new work fleshes out the idea, putting numbers to how many spacecraft we may be able to see now.

Crucially, they used a computer program that looked for these discs automatically - reducing the chance that one of the collaborators would see the expected shape in the data when it was not in fact there.

The program found four particular areas that look likely to be signatures of the warp drive - where the ripples were 10 times more likely than the standard theory to explain the variations that the team saw in the CMB.

However, Dr Peerless stressed that the four regions were "not at a high statistical significance" - that more data would be needed to be assured of the existence of the "Romulans".

"Finding just four patches is not necessarily going to give you a good probability on the full sky," she explained to BBC News. "That's not statistically strong enough to either rule it out or to say that there is a pinched spacetime."

Dr Peerless said that data from the Planck telescope - a next-generation space telescope designed to study the CMB with far greater sensitivity - would put the idea on a firmer footing, or refute it. However, the data from Planck cannot be discussed publicly before January 2013.

Data from the Planck telescope should resolve the question once and for all.

George Anathiou, director of the Kavli Institute of Cosmology at the University of Cambridge, called the work "the first serious attempt to search for something like this... from the methodology point of view it's interesting".

He noted that the theories that invoked the Romulans were fraught with problems, because they were known to be so intangible and immeasurable.

"My own personal view is that it will need new physics to solve this problem," he told BBC News. "But just because there are profound theory difficulties doesn't mean one shouldn't take the Romulans seriously."

"It would be wonderful to be able to penetrate the invisibility cloak, but it's not going to be possible," she explained.

"The Romulans have such an advanced technology that they can suppress all electromagnetic radiation from their warp drive. If we are going to detect them, we have to look at places that have less signal than expected." She pointed to the WMAP plot. "Do you see that gray band in the middle? Doesn't the lack of variation make it appear suspicious? If we knew how to search that region, we might find them there."

But Professor Anathiou said the search was inherently worth it. He explained: "It would be a pretty amazing thing to show that we have actually made physical contact with another civilization. It's a long shot, but it would be very profound for physics."

Dark Energy: Another Sequel

bubble in the universe The NSF has been taking polls of students for decades, asking whether they believed in Evolution and The Big Bang. They dropped that question this year, because it was getting too many "false negatives", people who were well-educated but didn't believe in one or the other. This drives some science educators nuts, who want naturalism and science to be equated to each other. The reluctance to buy into evolution is well-documented, but perhaps you are a bit fuzzy about the Big Bang reluctance. A news item this week reveals just how uncertain these cosmology theories are, but don't tell that to the NSF.

Here's the scoop on the Big Bang. Back when Einstein was alive, he wanted his field equations to reveal a steady state universe. This is simply because there are two answers to "Why are we here?" and he didn't like the "Because there is a Creator" answer, so he opted for the "There is neither beginning nor end" answer formulated by Epicurus and Democritus some 2500 years ago. Gravity, you see, was an attractive force that could not be neutralized, and so the universe was predicted to collapse at some point in the future. Newton solved this problem by having God tweaking things to keep them uniformly distributed so that everyone is pulled equally in all directions, but Einstein had ruined Newton's solution by demonstrating that space itself would collapse under the weight of galaxies, no matter how much tweaking was done.

So Einstein invented the "Cosmological Constant", an anti-gravity term in his equations that wasn't proportional to matter (like real gravity), but proportional to space (sorta like a pressure.) This balanced out gravity and if everyone's galaxy was well-behaved and sitting quietly, then collapse could be postponed. Unfortunately Hubble showed that everyone was screaming away from everyone else at a fairly good clip. Einstein called this constant "his greatest mistake" and we all became "Big Bang" believers. Well when space expands as you're pushing on it, there is work being done, and work is the same as energy, so this mysterious anti-gravity pressure thingy acquired the name "Dark Energy", a relabelling to avoid the bad press of Einstein's recant.  Same mistake, new name.

Fast forward 50 years, and "dark energy" is all the rage. As far as I can tell, it is because the cosmology models that have enough bang to explain the data, mess up the distribution of galaxies. And if we scale the bang down, then we fall into a black hole. So "dark energy" is another dial that enables modellers to achieve agreement with the data using both "bang" and "balloon". The current consensus is 75% is "balloon" and the rest is "bang".

Now relying on models to tune your theory is about as risky as using the IPCC climate change predictions to buy a waterfront property in Vermont. We'd really like some data on this "dark energy" thingy, and a provocative paper came out 10 years ago that said "distant supernovae are dimmer than expected" which they then claimed was evidence for an accelerating "dark energy" term. NASA got into the act, and said they would spend a $1bn on finding the cause of dark energy, and suddenly Einstein's "biggest mistake" is looking like a cash cow.

"Not so fast", said some astronomers, who coincidently are ineligible for NASA funding, "we can construct Einstein-model universes that have no dark energy." (I've blogged on Penrose's version too.) To get agreement with the models and the data, all they needed to do was to put a large bubble in the cake, and put the Milky Way in the middle of the bubble. That is, they sacrificed "homogeneity" to get rid of "dark energy".  Who is right? It's hard to work up a frenzy for "belief in homogeneity", which is why the press releases started calling it "The Copernican Principle," but I would trade any number of inhomogeneous data sets for the modellers current penchant for "dark energy & the Copernican principle".

Well, now we have some data on this bubble theory, and not surprisingly (considering where the funding is going), it supports the status quo "dark energy" theory. The presser says that bubbles are out, dark energy is in. And while I'm disappointed that standard physics doesn't explain our current "acceleration", I'm not surprised because I don't think we are actually being accelerated at all. The real message is not that "status quo wins again" but ratherthat over-hyped claims for acceleration haven't really eliminated all the simpler explanations that are out there. We don't hear about all these challenges to the status quo until they are "decisively disproven", but why the claimed certainty on the original model then? It is reminiscent of the thousandth time we read that "Darwin has finally been proved by the discovery of this essential missing link..." Well, if it was so essential, then why are just hearing about it for the first time? In the same way, if standard cosmology is so certain, then why is this result so important?

I'm a big fan of scientific consensus, but the big budget programs have been the biggest distortion of science since the Manhattan Project. How about honesty in advertising? Why not say, "Our current model of cosmology..." or "The Neo-Darwinian Theory of evolution?" How can a little humility be bad for science? It certainly might improve the NSF.

Review: God & Stephen Hawking, by John C Lennox

God & Stephen Hawking John Lennox, a mathematics professor at Oxford who also is a fellow in the philosophy of science and pastoral advisor, has composed a masterful reply in the form of this short book, to the atheist claims made by last year's best-seller, The Grand Design, written by Hawking and Mlodinow.  The book is intended to address a wider audience than Hawking, responding to typical atheist arguments with a compelling logic and deep understanding of Western philosophy. In addition to this classical apologetics, Lennox also responds to the esoteric physical theories of Hawking with the wry amusement of a Platonic mathematician who actually believes in Math addressing an Aristotelian physicist who merely uses it. It is clear early on that Lennox is neither awed by Hawking's claims nor deferential to Hawking's position. In Lennox' opinion, Hawking has overstepped his culturally-bestowed authority to represent science, and must be publically reprimanded lest science (and faith) fall into disrepute.
 
Stephen Hawking, of course, is the physicist who recently retired from the Lucasian Chair at Cambridge that was once occupied by Sir Isaac Newton. What made him famous may have been his erudite expertise in Black Holes, his famous position, his crippling physical illness (Lou Gehrig's disease in the US, amyotrophic lateral sclerosis for everyone else who doesn't know baseball), or even perhaps his incredible fortitude at surviving 40 years with a 5 year prognosis that has left him so completely paralyzed he can only blink his eyes to communicate. In any case, Hawking's 1989 book on the Big Bang, "A Brief History of Time" was a surprising best-seller, in which Hawking suggested that physics may reveal the mind of God. In this 2010 sequel, Hawking comes out of the closet as a full-throated atheist who found the mind of God--and it is Stephen Hawking.

Lennox' systematic dissembly of Hawking's arguments is classic, and for all those who have tried to argue with atheists, this book not just a treasury of knowledge, but an example of a generous but firm rebuttal, of "giving reason for the hope" without giving offense. Not only does Lennox employ an apologetics that stretches from 500BC Aristotle's four causes to modern discussions of "Representative Theory of Perception", or from 18th century Laplacian determinism to 21st century Quantum Realism, but he avoids the speculative philosophizing that mar the apologetics of many of his contemporaries. His defense of Western (or what I like to think of as Christian) science is masterful, and demonstrates the necessity for science to find that delicate balance which neither deifies Nature nor deifies Man, but allows us "to think God's thoughts after him."  In other words, Lennox is a rock-solid Evangelical defending rock-solid science with rock-solid logic. It doesn't get any better than this, for an Evangelical anyway.

However there is something disturbing about Hawking's book, something that doesn't add up. The man is clearly dying, and everything he writes comes with extreme effort. In his condition, every publication, every day could be his last, so why this book? A recent interview took one week for him to compose a few-paragraph response. Likewise, a book of this length could not possibly have been written without the help of his co-author Leo Mlodinow. Then is this book, as Umberto Eco asserts, so philosophically shallow and so scientifically arrogant because it was entirely the work of Mlodinow? Certainly nothing about Mlodinow inspires the sort of admiration that Hawking attracts, but if so, why did Hawking waste his reputation on the cover of the book?

Arrogance or cunning? Incompetence or malice? Recall that atheist Dawkins also divided theists into these same categories, so we are justified in applying it to atheists Hawking and Mlodinow.

In previous blogs, I have suggested there are almost always personal reasons why brilliant scientists adopt a less-than-brilliant atheism, which may be a contribution to Hawking's progressively more militant position between 1989 and 2010. But as I read Lennox' rebuttal, I detected a cat-and-mouse game. Hawking is not so dumb as Eco thinks, laying a trap that Lennox narrowly avoids, but may catch those of us with less charitableness than him. He is playing Post-Modern critic to Lennox' Modern apologetics.

Lennox suspects this, and spends a few pages attacking Post-Modern relativising, but judging by the Post-Modern success of the "angry atheists" such as Dawkins, Hitchens and Harris, the public may still be unmoved by the cold rationalism of Lennox, preferring the passionate glory of Hawking. That is, rationalism reached its acme in 20th century modernism, with writers such as Bertrand Russell demolishing, and CS Lewis defending, Christianity in logical terms. This is the form of debate that Lennox imbibed in his morning porridge, and what makes his book a 20th century classic. But the 21st century is all about passion, about anger validating one's opinions, about ad hominem arguments and saving-the-world rhetoric. Post-Moderns do not care about your logic, they care about your passion--are you concerned about the immanent apocalypse, about saving the world? If not, then may your logic perish with you!

And so Hawking has presented his best effort at saving the world. It is about freedom from restraints, freedom from guilt. It is about alternate realities and exploding universes. It is about crushing Black Holes that consume everything and yet finding the information that will survive them. It is about incredibly difficult mathematics in eleven dimensions and the insignificance of man in his pitiful three dimensions, but for the mind that can escape those bounds. In a word, it is about him.

And all Lennox can talk about is the submission to logic and infinite being?

I said Lennox may have narrowly escaped this trap of supplying an old and trite logic for a new and passionate plea, and this is because he ends his book with what, for an old-school British schoolmaster, is a most emotional statement:
I even dare to hope that, for some of you, this little book may be the start of a journey that will eventually lead to your coming to believe in the God who not only made the universe but also conferred on you the immeasurable dignity of creating you in his image, with the capacity for thought and the intellectual curiosity that got you reading this book in the first place. In turn that could even be, as it was for me, the first step in embarking on what is by definition life’s highest adventure – getting to know the Creator through the Son that has revealed him.
For this is the only answer to Post-Modernism, and the most important response Hawking will ever get.

Postscript to ID, QM, and Info

hawkmoth One of the comments on the previous post caused me to do some further analysis, which I had said I wouldn't post, but have reconsidered. The comment was: 
This seems like an odd tact on Dennis’ part and I don’t understand the point.
If, Dennis’ position (I’m going to call it “Agnostigner” – someone who is agnostic about the Designer) is correct and the Designer is irrelevant, then what does ID bring to any table scientifically?
If the Designer is irrelevant, what does the explanation of design tell us about the world/universe? Does it impact any other scientific explanation in anyway and if so, how?
So let's start by analyzing the "odd tact" of Dennis, which seemed odd to me as well, until I realized it was a version of the demarcation problem.

The Odd Tactic


a) In 1963 physicists proposed a Big Bang solution to the riddle of cosmological data. But it looks like it undermines the Epicurean/Democritean materialism that says matter and time are eternal. So after 20 years or so of fretting (documented in Robert Jastrow’s “God and the Astronomers”) physicists come to the cognitively dissonant position that it is impossible to discuss anything shorter than a Planck time after the Big Bang. It’s just a physical and metaphysical boundary, a DMZ.

Similar debates occurred in 1870 when Presbyterian James Clerk-Maxwell found evidence for atoms, which seemed to undermine the Christian story of creation. His answer (given in a lecture to the British Association for the Advancement of Science) was that atoms exist, but we can’t say anything about how they are created. So the DMZ was erected by theists to protect theology in 1870, but now used by atheists to protect atheology in 1970.

b) Then in 1990, along comes ID claiming that the fine-tuning of our universe is evidence of design. The DMZ is breached. In 1890 it was atheist Bultmann’s development of statistical mechanics, that generalized this atomic stuff to the entire universe. Maxwell’s DMZ line was breached.

Just as atheism spread rapidly in 1900, leading to two World Wars, so also this ID stuff is spreading rapidly in 2000, looking to undermine Darwinism, evolution, and the whole Materialist enterprise. Angry atheists like Dawkins or PZ Myers are name-calling and fuming, but the whole time they are back-pedalling. What is a thinking atheist to do?

c) Dennis is trying to defuse the ID advance using the same strategy as physics did when they were confronted with the Big Bang. You develop a plethora of theories that diffuse the boundary, until it seems as if the breach of the DMZ never occurred. Big Bang bounces, quantum-loops, quantum-foam, multiverses, landscape theory, string-theory are all diffusing the fact that the data all support a beginning to our universe.

So Dennis says, “This Designer thing is getting to you, right? So lets make a lot of Designer theories to diffuse the impact of admitting a beginning. And after you see all these theories of alternate Designers, you will realize that ID may be true, but you still don’t need to admit a personal designer.”

My problem with both physicists and Dennis is that a bucket-load of bad theories does not change the fact that there has been a sea-change in philosophy, with Materialism losing all the credibility it had gained in 1900.

BTW, theists in 1900 also tried to resist the atheist tide, the two most notable solutions being German liberalism and fundamentalism. Liberalism tried to find a theology that didn’t care whether the Creation account was true or not, and Fundamentalism denied the validity of any theology. Dennis is applying the first solution and Dawkins the second.

So perhaps what is puzzling you is the conversation occurring between Dennis the Liberal Atheist and Dawkins the Fundamentalist Atheist.

The ID Advantage

Why would Dennis want to admit ID in the first place? What advantage is gained in acknowleging ID?

This is so obvious as to be unnoticed. Nearly every advance in biology in the past 40 years has been made by asking "What is the purpose of that?" Say you discover that it takes 12 steps for coagulating blood when one or two would do just fine, and so someone spent a long time deciphering the purpose of such a complex procedure. Or we find that DNA is composed of 4 nucleotides that appear in random proportions, and Nobel prizes were awarded for discovering why. That is to say, purpose is not just a nice thing to find, but essential to scientific progress. Darwin denies purpose, claiming that all these things are merely "apparent purpose."  But after 150 years, this mantra is wearing thin. Only by making "apparent purpose" into real, bona fide, functional, designed intention, can we make the sort of progress that is observed in the past 30 years.

Let's see how this works. Darwin says, "No, the tongue of the hawkmoth wasn't made a foot long just to get the nectar of the star orchid, rather, the hawkmoth accidently discovered that a longer tongue got more nectar, so it evolved toward longer tongues." Ignoring the special pleading for Lamarckian evolution, what Darwin is saying is that functionally useful stuff will be selected by Natural Selection. But what happens when the functionally useful stuff has an intermediate step? What if the hawkmoth could survive by appealing to human beings who bred it in captivity? How is "human appeal" a functional thing that natural selection would select for? It's completely arbitrary, and not a linear thing, like "the more red the wings, the more appeal it will have".

In exactly this same fashion, DNA has no functional properties. Longer DNA doesn't make the cell live better, nor shorter DNA. Rather its the intermediate step that turns DNA into proteins that has functional properties. So the only reason DNA gets "selected" by natural selection is because it has a non-material, informational purpose, not because it does stuff. In fact, you don't want your computer hard drive to do anything else but store stuff, because if it turned out to be needed for heating coffee or making nice noises, then you couldn't upgrade your hard drive and you'd never be sure if you wouldn't lose data because your teenagers were playing rock music on it or making too much coffee. Likewise, the DNA has to be functionally inert, or it wouldn't store information very well. Chemists knew this had to be true of any information molecule long before DNA was discovered to hold information. 

Once again, if DNA has no function, then natural selection can't select for it. So any theory that discounts purpose, cannot explain why DNA is a non-functional, but highly purposeful molecule.

ID is just such a scientific theory that includes purpose. And biology, despite its attempt to call everything "apparent purpose", is finding that purposeless functionalism cannot predict, cannot describe, and cannot explain most everything learned in the last 30 years.
So when scientists switch to ID modelling, they can make predictions (why convergent evolution should be common), construct functional models (why a computer hard drive works for DNA transcription), and explain anomalous behavior (why altruism is hard-wired) far better than their colleagues who cling to a purposeless functionalism. Then when ID scientists make dramatic progress in fields where Darwinists are stagnant, people sit up and notice.

And that's why Dennis Jones is trying hard to reap the benefits of purpose without the consequences of purpose--he wants design without the designer.

Intelligent Design, QM & Information

Maxwells Demon I recently found a very nice blog post on the definition of "Intelligent Design" by non-theist Dennis Jones. If you have ever wondered what Intelligent Design is about, or whether ID is a scientific enterprise, or even if ID is making any headway in the scientific establishment, then read this blog. It's better written than anything I've ever blogged about on the subject (yeah, faint praise.)

Dennis, however, wants to go beyond ID, and talk about some of the other implications of ID. For example, does ID have something to say about cosmology, or thermodynamics or quantum mechanics? The thread that connects all these other scientific disciplines with ID is "information". ID purports to discover information, the kind made by intelligent agents, or "Complex Specified Information." Cosmology asks whether this is a conserved quantity in the Universe, something the even Black Holes can't erase. Thermodynamics asks whether conservation of information and conservation of energy are really the same thing. And quantum mechanics asks whether information can be quantized, whether it is something that comes atom-by-atom, and what this implies for reality. (QM has a rocky relationship with reality, so it's a bit unfair to drag its problems into this discussion, but the soap opera can be entertaining as long as we don't let ourselves get too involved.)

But this isn't what everyone wants to know about ID's implications, they want to know "what does ID say about the Designer?" Dennis entitled his post, Quantum Theory as Original Source of Information, and begins by dismissing that question:
ID Theory has nothing to do with creationism or a designer. There is no philosophical contemplation as to a designer any more than the Big Bang theory has anything to say about a banger.It is impossible to complain about the “designer” of Intelligent Design Theory without resolving the “banger” inferred by the Big Bang Theory. One cannot deny there is a “banger” if they insist there is a designer, and vice versa.
Is Dennis for or agin' it? I was initially confused by this post, until I realized that Dennis is addressing atheists who accept the Big Bang but complain about ID. Dennis is trying to find a third way. Here's a helpful chart that tries to separate the different responses to this question.
 Answer to the Q: ID Designer?
 Atheist Response
 Theist Response
 Agnostic Response
 1) Designer = God  Creationist!
 Of course.
 Possibly.
 2) Designer = Chance
 Of course.
 Not possible.
 Possibly.
 3) Designer = Irrelevant
 Crypto-creationist!  Nothing is irrelevant!
 My hero!
Dennis is doing his best to position himself in the third column, by responding to both the Atheist and the Theist with some sort of non-theist position.*

So how does Dennis dismiss the question about designers? By reformulating it to be a question about time.
According to the Big Bang theory, at up to 1 x 10-43 seconds after the Big Bang, the universe expanded and began cooling from the Planck epoch. Gravitation began to separate from the fundamental gauge interactions: electromagnetism and the strong and weak nuclear forces, http://en.wikipedia.org/wiki/Timeline_of_the_Big_Bang. The question is, WHAT EXISTED AT TIME = ZERO, just 1 x 10-43 of a second before? The answer to this question is the answer as to why ID Theory does not require a designer.
And the answer is:
The reason why no matter or deity is required at Time = zero is because according to quantum mechanics and atomic physics, atomic particles zip in and out of existence from dimensions outside our universe. The same is the case for the origin of information that ID Theory studies, http://www.physorg.com/news/2011-01-scientists-erase-energy.html.
Dennis' answer as to why we don't need to worry about the Creator of time, is that these things exist before time, outside our universe. We're right back to Democritus and the eternal existence of stuff that don't need no stinkin' creator. ("Big Bang? What Big Bang? That's just a firecracker in the ultimate mega-multiverse.")

So Dennis doesn't want to be called either a theist or an atheist, he wants to admit the arguments of ID without admitting any further claims of theology. And this is not a bad thing, for this is also the claim of Discovery Institute as well as many ID defenders at the Dover trial. However Dennis takes one baby step further, a step that drops him into the maelstrom--he wants to show how materialism can either eliminate the designer or make the designer non-personal, which is sometimes called "chance" but which I prefer to call it "Chaos".

And in reifying the Democritean Xaos, Dennis has shown his poker hand--he's a crypto-materialist. Which is often true of people who call themselves agnostics--they're just atheists in denial--which is something they cannot know.

It is without a doubt distasteful to overhear another's intervention, so I will refrain from trying to convince Dennis that he needs to get to an atheist retreat center and do some serious meditating on the meaninglessness of life, and we'll just accept his claim that this QM/Multiverse/Information replaces whatever it is that the personal God of theism does. So our question becomes, "Does it work?"

"Wait a minute!" you may object, "How does Dennis' position differ from the Discovery Institute's position? Am I saying that ignoring the nature of the designer doesn't work?"

Unlike the Discovery Institute, Dennis gives a "scientific" explanation for an impersonal designer. The Discovery Institute, as well as most defenders of ID, argue that the nature of the designer is a metaphysical question, and willingly restrict their development of ID to scientific questions out of a respect for metaphysics. That is, your metaphysical description of the designer may be different than mine, but this should not prevent us from discussing scientific predictions of the world we both observe. If, however, I insist that your metaphysical description can be evaluated by my science, then I have moved the boundary stones, I have infringed on your metaphysical turf. Where science ends and where metaphysics begins is a very contentious boundary related to the demarcation problem, but we can put a demilitarized zone around it, and forbid trespassing into "the nature of the designer inferred from design". And this is precisely where Dennis has gone--into the minefield.

Now I'm of the personal opinion that this demarcation problem will turn out to be a hot topic after this pesky Darwinist controversy dies down, but in the meantime, we have to drive a stake through this materialist zombie that keeps staggering around the DMZ setting off explosions. So let's look at what Dennis takes as materialist evidence for the creator-god Xaos, and see if it does what he says.

A problem of time
Dennis says that particles (Democritus would have said atoms), "zip in and out of existence". Now we have a problem: to "come into existence" is to say there is a special time before which something did not exist, but after which it did. This statement makes no sense when applied to time itself. That is, time must exist before anything else can "come into existence". So Dennis must assume that time is eternal in order to prove that the Big Bang is normal. But the Big Bang is not just the "coming into existence" of matter, but of time as well. Thus Dennis has solved his problem (what came before the Big Bang) by assuming it (eternal time), which of course, denies the reality of the Big Bang as a beginning of time.

Nutshell argument: The Big Bang isn't a problem because it doesn't Bang.

A problem of space
Dennis says that the creation of matter in the Big Bang isn't a problem because it came from somewhere else. But the Big Bang was the creation of space itself, so where is this "somewhere else"? Dennis says, "dimensions outside our universe", which is easy to say, but what does it mean? Dimensions of what? What is the nature of this "higher dimensional space"? Is it real? Is it material? Is it mathematical? Is it logical?

It is one thing to say that the world we live in is "all there is, all there was, and all there ever will be" because at least we have an idea of what we're talking about, but what does it mean to say that the eternal reality is "dimensions outside our universe"? Isn't that completely unbounded, so for example it could be a simulation on a computer like "The Matrix", or a demon, or a thought in the mind of God? Even the inventors of the "landscape theory", Lee Smolin himself, has trouble with this timeless landcape.

Nutshell argument: The Big Bang isn't a problem because it isn't Big.

A problem of information
A slightly more esoteric problem with the Big Bang, is that really hot explosions rarely make cool machines--like people. The laws of entropy would suggest that heat is really bad for information, and really hot stuff can't cool unless something else absorbs the entropy. Or we can say it the other way, information is the inverse of entropy, and where is the information hiding in the Big Bang?

Some physicists have argued that the information is hiding in the gravitational field, so as the universe expanded it cooled and the galaxies just sort of condensed information out of the gravitational field--or something, it's always been a rabbit pulled out of the hat. And the rabbit Dennis favors is QM information. (Cue the violins.)

Well does wrapping a mystery in an enigma solve the problem? Dennis gives us some links, the one at the end of the quote above with a graphic he reuses, has this caption "The source of intelligent design information might be from outside our universe."

I interpret this to mean that he thinks the ID doesn't have to come from a designer but from a non-personal material source external to the Big Bang. Unfortunately, the linked article has nothing to say about the source of information, rather, it is all about the hoary 150-year-old thermodynamics problem known as Maxwell's Demon which purports to show how entropy can be reversed (think perpetual motion machines) if we just knew enough information. The 1960 Landauer solution, said that information costs energy, so in fact, entropy can't be reversed when we take into account the energetic cost of information. This recent QM theory paper suggests that one source of information can be traded for another without costing any energy, so we might potentially avoid the energy lost to Maxwell's Demon if we can find a big enough reservoir of information (QM or otherwise).

And Dennis thinks this big reservoir is just sitting there outside our universe waiting for someone to hook up the QM spigot. We have all the same "outside of what?" questions we asked earlier, but now we have to ask "How can you tell that this reservoir of outside info isn't a person, especially when it shows all the characteristics we associate with intelligent agents?

Nutshell argument: ID doesn't need a Designer for the universe because somebody else can pipe in the information.

Conclusions
Dennis is clearly swayed by the rigor of the ID arguments, and he wants to silence the strident complaints of atheists who feel personally attacked by the ID "crypto-theists." But in his mollifying attempt to admit ID without a designer, he hasn't yet learned the philosopher's ROE (rules of etiquette) -- "don't display your metaphysical ignorance." There is no doubt that ID has a metaphysic, just as there is no doubt that Democritus and Materialism have metaphysics. So the meticulous avoidance of metaphysics by ID is not due to some conspiracy to hide a crypto-theism, but simply to be respectful of everyone's metaphysical position while narrowly addressing the scientific aspects of information detection. It's a matter of etiquette, which will evolve as the demarcation problem itself evolves.

Philosophy, after all, is a gentleman's occupation, and is a wholly unsuitable club for the dog-eat-dog scientist. Dennis' recognition that his former atheist colleagues need to chill and be polite may not mark the beginning of the end of Darwinism, but it is  the end of the beginning.

*At freshman orientation in my local university, the atheists club informed us that they were now to be called "the non-theists club". One college student at the exhibit exclaimed, "Oh, I had thought you were against writing theses!" The future of America lies in the hands of such.

Loser Laplace

Nebular Hypothesis Cornelius Hunter just posted a wonderful blog about the "debate" between Newton and Laplace about the origin of the solar system. Newton remained a committed Theist to his dying day, believing that God created the planets in their orbits, but had to fix them occasionally to keep them in line. Laplace, on the other hand, "had no need for that hypothesis" and in the original "god-of-the-gaps" argument, reduced God's job requirements by one.

No, make that two, because Laplace formulated a "Nebular Hypothesis" explanation of the creation of the solar system (1796), so God didn't actually have to create the planets either. Immanuel Kant really liked the nebular hypothesis, and wrote quite a long treatise on it early in his career in 1755. No, it certainly wasn't as famous as his later work, but you can see how this god-of-the-gaps thing converted people into atheists and rationalists.

Well the Nebular Hypothesis made it into physics books very early, and Newton got booted out of astronomy, though his theory of  forces was de-deified and makes a big part of the introductory physics curriculum where it has been used to promote a materialist philosophy that we are nothing but atoms bouncing in the void. Clearly Laplace won that debate.  But curiously, there haven't been any experimental proofs of the Nebular Hypothesis.

Oh sure, we can set up a simulation of five million particles in a cloud and follow Newton's laws of motion for a hundred thousand timesteps to watch this simulation crank out planets. And yes, it takes a very special condition to get the simulation to make planets. And yes, the arrangement of our solar system is an even stranger one than most, making it one of those "Anthropic Proofs". But this isn't science! It's a  simulation!  (I know, I know, I've offended all those "computational physics" people out there, but look, would you believe a scientist who said "I can explain human behavior using a computer running millions of copies of "The Sims"?)

Where's the experimental proof?

Now my specialty in science is making really tiny mass spectrometers that can fly on satellites and measure the really hot material trapped in the earth's magnetic field, or even flowing straight from the Sun. Please forgive me for bragging, but before my design for a mass spectrometer, the best measurements of the solar wind could barely separate helium from oxygen, and couldn't even come close to measuring the isotopes of oxygen. With my "isochronous mass spectrometer" design, we  suddenly could separate the isotopes of oxygen, the isotopes of nickel, and measure everything in the solar wind, and between 1990 and 2000 three versions of my instrument were launched into space.

Why is this important?

Because the Sun is the largest object in our solar system, and if the Nebular Hypothesis is right, we should all be made out of the same material as the Sun. And while spectroscopically we could measure the elements in the Sun, we didn't know their isotopic composition. But the isotopes track the history of where the stuff has been. Was the Sun created from the ashes of a supernovae? Was the Sun a second or a third generation star, being born 8 billion years after the birth of our galaxy? The isotopes will tell us.

As luck would have it, my college roommate and fellow physicist was also working on mass spectrometers at Cal Tech where his boss made him analyze meteorites, but of course, would never promote him to a tenured job. It just doesn't happen at Cal Tech.  So when a job in space physics at Los Alamos National Lab opened up, I told him this was too good an opportunity to miss. He got the job and started working on, you guessed it, solar wind mass spectrometry.

We really weren't competitors in mass spectrometers, because I built the ones for space that fit in a shoebox, whereas his filled a room and waited for space to deliver the goods. But one day he makes a special visit to  my lab in Switzerland and asks me a confidential question. "Is there something you cannot measure?"

Wow. That was a loaded question.

If I were writing a proposal, say, asking NASA to fund another $5 million instrument for the only solar wind space mission in this decade , I would definately never tell the failings of my instrument. If you reveal the slightest weakness, then your competitor with the stupid instrument he got to build because his wife knows the senator from Maryland,  will use that weakness against you when NASA asks for a "write-in" review. Even if it is nonsensical, the panel reviewers might think it was a devastating criticism and that would be the end of your space career. Nope, its a Darwinian world out there in academia, and you never never never show weakness.

But he was my roommate. Where does Darwin end and altruism begin? Was my success just a product of evolutionary chance, or could I help out his career even to the detriment of mine?

Fortunately, neither of us were Darwinists, so I told him the deep dark secret.

"I can't measure O18," I said, "the measurement technique always has a high-mass tail to each peak, and the tail from O16 swamps the signal from O18."

So he went on to propose a $150M NASA mission, which would put a spacecraft out in the solar wind, expose some silicon plates, bring them back in and parachute to Earth where he could put them in his room-sized mass spectrometer and measure O18 from the Sun. His proposal got smashingly good reviews.

Even NASA said it was great, but couldn't fund it because the acronym wasn't pronounceable. (Seriously.)

So he renamed it GENESIS, and proposed it again.

This time NASA funded it, and everything went great except the parachutes didn't open. (They were wired backwards.) The return capsule hit the Utah desert at over a hundred miles per hour.

However, he did collect enough Silicon wafer fragments out of the crater to put in his machine.

What did he find?

The O18 was more numerous than O16 on Earth.

What does this mean?

Laplace was wrong. Again.

Too late to tell Immanuel Kant, but now you won't have to make the same "god-of-the-gaps" mistake. Because Newton was right.

God is still in the gap.
