Dr. Robin Collins explains two kinds of cosmic fine-tuning

6 Comments

I was busy working my way through “Debating Christian Theism“, a book published by Oxford University Press in August 2013. It features about 20 different topics from science, to philosophy, to history. For each topic, there is an essay by a world-class scholar in favor, and one opposed. So you get both sides of many interesting issues, at a very advanced level. The section on cosmic fine-tuning features a chapter written by Dr. Robin Collins.

About Robin Collins:

Robin Collins (PhD, University of Notre Dame, 1993), is professor of philosophy at Messiah College, Grantham, PA specializing in the area of science and religion.  He has written over twenty-five articles and book chapters on a wide range of topics, such as the fine-tuning of the cosmos as evidence for the existence of God, evolution and original sin, the Doctrine of Atonement, Asian religions and Christianity, and Bohm’s theory of quantum mechanics.  Some of his most recent articles/book chapters are “Philosophy of Science and Religion” in The Oxford Handbook of Science and Religion, “Divine Action and Evolution” in The Oxford Handbook of Philosophical Theology (2009)  “The Multiverse Hypothesis: A Theistic Perspective,” in Universe or Multiverse? (Cambridge University Press), and “God and the Laws of Nature,” in Theism or Naturalism: New Philosophical Perspectives (Oxford University Press, forthcoming).  He recently received a grant from the John Templeton Foundation to finish a book that presents the case for design based on physics and cosmology,  tentatively entitled The Well-Tempered Universe: God, Cosmic Fine-tuning, and the Laws of Nature.

The fine-tuning argument

Here’s a short article where Collins gives TWO examples of the fine-tuning. He is very modest in his argument, merely asserting that the fine-tuning is more compatible with theism than it is with atheism.

Excerpt:

Science is commonly thought to have undercut belief in God. As Nobel Prize winning physicist Steven Weinberg famously remarked, “the more we find out about the universe, the more meaningless it all seems.” Yet, the discoveries of modern physics and cosmology in the last 50 years have shown that the structure of the universe is set in an extraordinarily precise way for the existence of life; if its structure were slightly different, even by an extraordinarily small degree, life would not be possible. In many people’s minds, the most straightforward explanation of this remarkable fine-tuning is some sort of divine purpose behind our universe.

This fine-tuning falls into three categories: the fine-tuning of the laws of nature, the fine-tuning of the constants of physics, and the fine-tuning of the initial conditions of the universe. “Fine-tuning of the laws of nature” refers to the fact that if the universe did not have precisely the right combination of laws, complex intelligent life would be impossible. If there were no universal attractive force (law of gravity), for example, matter would be dispersed throughout the universe and the energy sources (such as stars) needed for life would not exist. Without the strong nuclear force that binds protons and neutrons together in the nucleus, there would not be any atoms with an atomic number greater than hydrogen, and hence no complex molecules needed for life. And without the Pauli-exclusion principle, all electrons would fall to the lowest orbital of an atom, undercutting the kind of complex chemistry that life requires.

Some fundamental physical numbers governing the structure of the universe—called the constants of physics—also must fall into an exceedingly narrow range for life to exist. For example, many have estimated that the cosmological constant—a fundamental number that governs the expansion rate of empty space—must be precisely set to one part in 10120 in order for life to occur; if it were too large, the universe would have expanded too rapidly for galaxies and stars to form, and if it were too small, the universe would have collapsed back on itself. As Stephen Hawking wrote in his book A Brief History of Time, “The remarkable fact is that the values of these numbers [i.e. the constants of physics] seem to have been very finely adjusted to make possible the development of life.” Finally, the initial distribution of mass energy at the time of the big bang must have an enormously special configuration for life to occur, which Cambridge University mathematical physicist Roger Penrose has calculated to be on the order of one part in 1010123. This is an unimaginably small number.

I know what you’re thinking: How do we know that non-Christian scientists acknowledge the fine-tuning of gravity in the way that Collins describes?

Well, the New Scientist actually talks about the fine-tuning of the force of gravity. And they’re not Christians.

Excerpt:

The feebleness of gravity is something we should be grateful for. If it were a tiny bit stronger, none of us would be here to scoff at its puny nature.

The moment of the universe‘s birth created both matter and an expanding space-time in which this matter could exist. While gravity pulled the matter together, the expansion of space drew particles of matter apart – and the further apart they drifted, the weaker their mutual attraction became.

It turns out that the struggle between these two was balanced on a knife-edge. If the expansion of space had overwhelmed the pull of gravity in the newborn universe, stars, galaxies and humans would never have been able to form. If, on the other hand, gravity had been much stronger, stars and galaxies might have formed, but they would have quickly collapsed in on themselves and each other. What’s more, the gravitational distortion of space-time would have folded up the universe in a big crunch. Our cosmic history could have been over by now.

Only the middle ground, where the expansion and the gravitational strength balance to within 1 part in 1015 at 1 second after the big bang, allows life to form.

Here’s a very long paper by Collins on the fine-tuning argument, where he answers several objections to the argument, including the multiverse/many-universe hypothesis. I normally make fun of the multiverse, (= the Flying Spaghetti Monster), but it actually does deserve a reasonable, fair response. (Unless Jerry asks, then it’s Flying Spaghetti Monster all the way).

Convergence detected in the genetic structure of bats and dolphins

8 Comments

We have to start this post with the definition of convergence in biology.

In evolutionary biology, convergent evolution is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.

It is the opposite of divergent evolution, where related species evolve different traits.

On a molecular level, this can happen due to random mutation unrelated to adaptive changes; see long branch attraction. In cultural evolution, convergent evolution is the development of similar cultural adaptations to similar environmental conditions by different peoples with different ancestral cultures. An example of convergent evolution is the similar nature of the flight/wings of insects, birds, pterosaurs, and bats.

All four serve the same function and are similar in structure, but each evolved independently.

Jonathan Wells explains the problem that convergence poses for naturalistic evolution:

Human designers reuse designs that work well. Life forms also reuse certain structures (the camera eye, for example, appears in humans and octopuses). How well does this evidence support Darwinian evolution? Does it support intelligent design more strongly?

Evolutionary biologists attribute similar biological structures to either common descent or convergence. Structures are said to result from convergence if they evolved independently from distinct lines of organisms. Darwinian explanations of convergence strain credulity because they must account for how trial-and-error tinkering (natural selection acting on random variations) could produce strikingly similar structures in widely different organisms and environments. It’s one thing for evolution to explain similarity by common descent—the same structure is then just carried along in different lineages. It’s another to explain it as the result of blind tinkering that happened to hit on the same structure multiple times. Design proponents attribute such similar structures to common design (just as an engineer may use the same parts in different machines). If human designers frequently reuse successful designs, the designer of nature can surely do the same.

I’m a software engineer, and we re-use components all the time for different programs that have no “common ancestor”. E.g. – I can develop my String function library and use it in my web application and my Eclipse IDE plug-in, and those two Java programs have nothing in common. So you find the same bits in two different programs because I am the developer of both programs. But the two programs don’t extend from a common program that was used for some other purpose – they have no “common ancestor” program.

Now with that in mind, take a look at this recent article from Science Daily, which Mysterious Micah sent me.

Excerpt:

The evolution of similar traits in different species, a process known as convergent evolution, is widespread not only at the physical level, but also at the genetic level, according to new research led by scientists at Queen Mary University of London and published in Nature this week.

The scientists investigated the genomic basis for echolocation, one of the most well-known examples of convergent evolution to examine the frequency of the process at a genomic level.

Echolocation is a complex physical trait that involves the production, reception and auditory processing of ultrasonic pulses for detecting unseen obstacles or tracking down prey, and has evolved separately in different groups of bats and cetaceans (including dolphins).

The scientists carried out one of the largest genome-wide surveys of its type to discover the extent to which convergent evolution of a physical feature involves the same genes.

They compared genomic sequences of 22 mammals, including the genomes of bats and dolphins, which independently evolved echolocation, and found genetic signatures consistent with convergence in nearly 200 different genomic regions concentrated in several ‘hearing genes’.

[…]Consistent with an involvement in echolocation, signs of convergence among bats and the bottlenose dolphin were seen in many genes previously implicated in hearing or deafness.

“We had expected to find identical changes in maybe a dozen or so genes but to see nearly 200 is incredible,” explains Dr Joe Parker, from Queen Mary’s School of Biological and Chemical Sciences and first author on the paper.

“We know natural selection is a potent driver of gene sequence evolution, but identifying so many examples where it produces nearly identical results in the genetic sequences of totally unrelated animals is astonishing.”

Nature is the most prestigious peer-reviewed science journal. This is solid material.

There is an earlier article from 2010 in New Scientist that talked about one of the previous genes that matched for hearing capability.

Excerpt:

Bats and dolphins trod an identical genetic path to evolve a vital component of the complex sonar systems they use to pursue and catch prey.

The finding is unusual, because although many creatures have independently evolved characteristics such as eyes, tusks or wings, they usually took diverse genetic routes to get there.

Analysis of a specific gene has now demonstrated that although bats live in air and dolphins in water, where sound travels five times faster, they independently evolved a near-identical gene that allows them to accept high-frequency sound in the ear – vital for sonar.

The gene makes prestin, a protein in hair cells of the cochlea, which is the organ in the inner ear where sonar signals are accepted and amplified. Prestin changes shape when exposed to high-frequency sound, and this in turn deforms the fine hair cells, setting off an electrical impulse to the brain. So the protein has the important jobs of detecting and selecting high-frequency sounds for amplification.

When researchers examined the molecular structure of the prestin gene from a range of animals, they found that the variants in echolocating bats and dolphins were virtually indistinguishable.

Indistinguishable genes in animals that don’t share a common ancestor? Maybe a better explanation for the evidence we have is – common designer.

Dennis Prager’s report from the recent conference on cosmic fine-tuning

10 Comments

My favorite national radio show host Dennis Prager in the National Review. This is a MUST-READ. (H/T Chris S.)

Full text:

Last week, in Nice, France, I was privileged to participate along with 30 scholars, mostly scientists and mathematicians, in a conference on the question of whether the universe was designed, or at least fine-tuned, to make life, especially intelligent life. Participants — from Yale, Princeton, Harvard, Berkeley, and Columbia, among other American and European universities — included believers in God, agonistics, and atheists.

It was clear that the scientific consensus was that, at the very least, the universe is exquisitely fine-tuned to allow for the possibility of life. It appears that we live in a “Goldilocks universe,” in which both the arrangement of matter at the cosmic beginning and the values of various physical parameters — such as the speed of light, the strength of gravitational attraction, and the expansion rate of the universe — are just right for life. And unless one is frightened of the term, it also appears the universe is designed for biogenesis and human life.

Regarding fine-tuning, one could write a book just citing the arguments for it made by some of the most distinguished scientists in the world. Here is just a tiny sample, collated by physicist Gerald Schroeder, who holds a Ph.D. from the Massachusetts Institute of Technology, where he later taught physics.

Michael Turner, astrophysicist at the University of Chicago and Fermilab: “The precision is as if one could throw a dart across the entire universe and hit a bullseye one millimeter in diameter on the other side.”

Paul Davies, professor of theoretical physics at Adelaide University: “The really amazing thing is not that life on Earth is balanced on a knife-edge, but that the entire universe is balanced on a knife-edge, and would be total chaos if any of the natural ‘constants’ were off even slightly.

Roger Penrose, the Rouse Ball Professor of Mathematics at the University of Oxford, writes that the likelihood of the universe having usable energy (low entropy) at its creation is “one part out of ten to the power of ten to the power of 123.” That is “a million billion billion billion billion billion billion billion billion billion billion billion billion billion zeros.”

Steven Weinberg, recipient of the Nobel Prize in Physics, and an anti-religious agnostic, notes that “the existence of life of any kind seems to require a cancellation between different contributions to the vacuum energy, accurate to about 120 decimal places.”

Life of any kind. Not just life as we know it, but life of any conceivable kind.

So the fine-tuning is real. It’s mainstream science.

But then how do militant atheists like Weinberg respond to this scientific data?

Unless one is a closed-minded atheist (there are open-minded atheists), it is not valid on a purely scientific basis to deny that the universe is improbably fine-tuned to create life, let alone intelligent life.

Additionally, it is atheistic dogma, not science, to dismiss design as unscientific. The argument that science cannot suggest that intelligence comes from intelligence or design from an intelligent designer is simply a tautology. It is dogma masquerading as science.

And now, many atheist scientists have inadvertently provided logical proof of this.

They have put forward the notion of a multiverse — the idea that there are many, perhaps an infinite number of, other universes. This idea renders meaningless the fine-tuning and, of course, the design arguments. After all, with an infinite number of universes, a universe with parameters friendly to intelligent life is more likely to arise somewhere by chance.

But there is not a shred of evidence of the existence of these other universes — nor could there be, since contact with another universe is impossible.

Therefore, only one conclusion can be drawn: The fact that atheists have resorted to the multiverse argument constitutes a tacit admission that they have lost the argument about design in this universe. The evidence in this universe for design — or, if you will, the fine-tuning that cannot be explained by chance or by “enough time” — is so compelling that the only way around it is to suggest that our universe is only one of an infinite number of universes.

Honest atheists — scientists and lay people — must now acknowledge that science itself argues overwhelmingly for a Designing Intelligence.

This is the same cosmic fine-tuning argument that is used by William Lane Craig in all of his debates. Are you surprised to learn that the top scientists from across the ideological spectrum agree with the fine-tuning? There is a reason why William Lane Craig can stand up in academic debates and make these arguments with confidence. The Big Bang cosmology and the fine-tuning of the Big Bang are two pieces of evidences for God’s existence that are as solid as any piece of science can be. To deny that the universe came into being out of nothing requires a leap of faith. To deny the cosmic fine-tuning also requires a leap of faith.

The simple fact of the matter is that God, in his infinite wisdom, left us this evidence which we have now discovered so that anyone who denies his existence and intelligence is without excuse. If atheists were making the decision about whether to believe in God solely based on science, then they would have to agree that the existence of God is beyond a reasonable doubt. We now know that God exists and created the universe for life for certain. The only reason to persist in unbelief now is because of non-rational concerns, e.g. – the desire to escape from moral obligations, childhood trauma, weak or absent father, etc.

You can read about some of the specific evidence for the origin of the universe out of nothing in this post, and you can read about some of the specific evidence for fine-tuning in this post.
