Thinkquote of the day: A showdown in the restaurant at the end of the universe?

In a recent article in the New York Times magazine, by Richard Panek, we read a very well written but surprisingly pessimistic assumption about what physicists can learn about the universe:
If so, such a development would presumably not be without philosophical consequences of the civilization-altering variety. Cosmologists often refer to this possibility as “the ultimate Copernican revolution”: not only are we not at the center of anything; we’re not even made of the same stuff as most of the rest of everything. “We’re just a bit of pollution,” Lawrence M. Krauss, a theorist at Case Western Reserve, said not long ago at a public panel on cosmology in Chicago. "If you got rid of us, and all the stars and all the galaxies and all the planets and all the aliens and everybody, then the universe would be largely the same. We’re completely irrelevant."
All well and good. Science is full of homo sapiens-humbling insights. But the trade-off for these lessons in insignificance has always been that at least now we would have a deeper — simpler — understanding of the universe. That the more we could observe, the more we would know. But what about the less we could observe? What happens to new knowledge then? It’s a question cosmologists have been asking themselves lately, and it might well be a question we’ll all be asking ourselves soon, because if they’re right, then the time has come to rethink a fundamental assumption: When we look up at the night sky, we’re seeing the universe.

The article argues that the universe may well be stranger than scientists can ever hope to understand.

The article is even a bit negative about string theory (we live in one of zillions of meaningless universes connected by strings):
And this [string theory] is just one of a number of theories that have been popping into existence, quantum-particle-like, in the past few years: parallel universes, intersecting universes or, in the case of Stephen Hawking and Thomas Hertog just last summer, a superposition of universes. But what evidence — extraordinary or otherwise — can anyone offer for such claims?


They want evidence? How extraordinary. Makes a nice change though.

(Note: Yes, in case you noticed, the Lawrence Krauss quoted on the subject of "pollution r' us" is one of the big anti- intelligent design guys. He is also down on string theory.)

It sounds, from the article, as though concepts like "dark matter" and "dark energy" must become more specific to provide useful information. This article is a must-read, though I don't go along with the underlying pessimistic assumption that maybe our limited senses prevent us from understanding these things. That sounds like Darwinism talking, actually. You know the sort of thing: We are just evolved apes and can't understand whatever is not in our genetic program to understand, including this problem.

Just think of all the areas of science that would not have got anywhere if the pioneers had taken such a view. That, incidentally, is why the Uncommon Descent blog's rationale says
Materialistic ideology has subverted the study of biological and cosmological origins so that the actual content of these sciences has become corrupted. The problem, therefore, is not merely that science is being used illegitimately to promote a materialistic worldview, but that this worldview is actively undermining scientific inquiry, leading to incorrect and unsupported conclusions about biological and cosmological origins.

Many universes: Or many fairies?

Casey Luskin noted a while back at Evolution News that a recent article in Nature noted that many universes theory is not testable:

Since the early 1980s, some cosmologists have argued that multiple universes could have formed during a period of cosmic inflation that preceded the Big Bang. More recently, string theorists have calculated that there could be 10 [to the]500 universes, which is more than the number of atoms in our observable Universe. Under these circumstances, it becomes more reasonable to assume that several would turn out like ours. It’s like getting zillions and zillions of darts to throw at the dart board, Susskind says. “Surely, a large number of them are going to wind up in the target zone.” And of course, we exist in our particular Universe because we couldn’t exist anywhere else. It’s an intriguing idea with just one problem, says Gross: “It’s impossible to disprove.” Because our Universe is, almost by definition, everything we can observe, there are no apparent measurements that would confirm whether we exist within a cosmic landscape of multiple universes, or if ours is the only one. And because we can’t falsify the idea, Gross says, it isn’t science. (Geoff Brumfiel, "Outrageous Fortune," Nature, Vol 439:10-12 (January 5, 2006).)


But, Luskin writes, “National Academy of Sciences member and Nobel Laureate Leonard Susskind was given print-space--in fact he had a highlighted box-quote--saying that we should not reject the multi-verse hypothesis on the grounds that it isn’t testable.” Nature reports:

Susskind, too, finds it “deeply, deeply troubling” that there’s no way to test the principle. But he is not yet ready to rule it out completely. “It would be very foolish to throw away the right answer on the basis that it doesn’t conform to some criteria for what is or isn’t science,” he says. (Geoff Brumfiel, "Outrageous Fortune," Nature, Vol 439:10-12 (January 5, 2006)


I love it! “It would be very foolish to throw away the right answer on the basis that it doesn’t conform to some criteria for what is or isn’t science ...” Why so foolish? Because, while it doesn’t conform to science, it does conform to materialism.

Similarly, in Max Tegmark’s 2003 Scientific American article on the four levels of multi verses, we are told that
Cosmologists infer the presence of Level II parallel universes by scrutinizing the properties of our universe. These properties, including the strength of the forces of nature and the number of observable space and time dimensions, were established by random processes during the birth of our universe. Yet they have exactly the values that sustain life. That suggests the existence of other universes with other values.


So the only reason for the Level II universes' supposed very existence is to avoid the obvious implications of observable fine-tuning in this one.

Now, of course there is no problem in principle with untestable theories being discussed.

The problem is that the many-universes hypothesis is used as a discussion-stopper - a way to avoid the fine-tuning of the universe.

Here's what it reminds me of: A small child claiming that "the fairies" broke the vase or stole the cookies.

The real problem isn't whether fairies exist or act - only a naif or a fool would try discussing that with the child - but whether "the fairies" are used to avoid addressing difficult sets of facts.

When dealing with such data sets in my own household decades ago, as a child minder and later a young mother, I usually resorted to the following judgement: "Well, if you know so much about the fairies, you must be part of their deplorable gang. You and they can spend the afternoon in your room, and I hope you enjoy each other's company."

Thinkquote of the day: Why you can take the Bible seriously but not literally on science issues

Mid-twentieth century scholar Bernard Ramm writes,
The language of the Bible with reference to cosmological matters is in terms of the prevailing culture. Biblical cosmology is in the language of antiquity and not of modern science, nor is it filled with anticipations which the future microscope and telescope will reveal. We do not agree with over-zealous expositors who try to find Einsteinian and modern astro-physical concepts buried in Hebrew words and expressions. We also disagree with the religious liberals who object to Biblical cosmology because it is not scientific. We object to the over zealous because it was not the intention of inspiration to anticipate modern science, and we object to the modernist because he sees too much in what is to us a truism. We concur with Calvin, who taught that Gen. 1 is a record of the creation of the world in the language of the common man and from the viewpoint of common sense. His actual words are: “For to my mind this is a certain principle, that nothing is here treated of but the visible form of the world. He who would learn astronomy and the other recondite arts, let him go elsewhere ... It must be remembered, that Moses does not speak with philosophical acuteness on occult mysteries, but states those things which are everywhere observed, even by the uncultivated, and which are in common use.” (John Calvin, Genesis, I, 79 & 84], quoted and discussed in B.L. Ramm, The Christian View of Science and Scripture , [1955] Paternoster: Exeter, Devon, 1967 reprint, pp.65-66)

Yes, and not just the Bible either. And not just in ancient times. Virtually every speaker of English refers to the sun "rising" and "setting," even though we all know that technically the Earth's rotation causes the appearance. But so? In the same way, we refer to bacteria, sowbugs, and flu virus as "bugs" even though none of them are insects. In the same way, a Biblical writer referred to the "ends of the earth." Did he know for sure whether the Earth had ends? So what if it doesn't? So what if the sowbug is really a crustacean like the lobster? Language choices are usually intended to convey an idea. It's the underlying idea we need to grasp.
