Brian Auten interviews philosopher Robin Collins on the fine-tuning argument

Here’s a must-listen interview from Apologetics 315.

Details:

Today’s interview is with Robin Collins, professor of philosophy at Messiah College. His training is in physics and in philosophy and he is a leading advocate for using the fine-tuning of the universe as a design argument for theism. He talks about his background and training, the fine-tuning argument, the different types of fine-tuning with examples and illustrations (laws, constants and initial conditions), two different ways of presenting the fine-tuning argument, answering common objections to the argument, the uniqueness of life, variations of the multiverse hypothesis, the failure of multiverse theory to explain away fine-tuning, objections to Victor Stenger, upcoming books, simplifying the fine-tuning argument for practical use, common mistakes when presenting the argument, the most common objection (who designed God?), and more.

Dr. Collins is extremely cautious and circumspect in his assessment of the fine-tuning argument. He takes the objections to the argument, like the multiverse, seriously and that comes across in the interview. He is familiar with criticisms of the argument and he has engaged with skeptics like Victor Stenger in his published work. I highly recommend it. It is a little more suited to intermediate-level Christians, but not so advanced that it’s impossible for non-math beginners to follow the broad thrust of what’s being said.

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 10¹⁵at 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.

If you want a longer response to the multiverse argument, but you don’t want to shell out big bucks for Collins’ chapter in the “Blackwell Companion to Natural Theology“, then you can just get James Sinclair’s essay in “Contending With Christianity’s Critics“.

Some examples of cosmic fine-tuning

Jonathan M. posted about the fine-tuning argument on the Apologetics UK blog.

Here’s the general argument:

The concept of cosmic fine tuning relates to a unique property of our universe whereby the physical constants and laws are observed to be balanced on a ‘razor’s edge’ for permitting the emergence of complex life. The degree to which the constants of physics must match precise criteria is such that a number of agnostic scientists have concluded that indeed there is some sort of transcendent purpose behind the cosmic arena. British astrophysicist Fred Hoyle writes: “A common sense interpretation of the facts suggests that a super intellect has monkeyed with physics, as well as with chemistry and biology, and that there are no blind forces worth speaking about in nature. The numbers one calculates from the facts seem to me so overwhelming as to put this conclusion almost beyond question.”

He goes into some detail about how the amount of mass of the universe has to be finely tuned to the volume of the universe, which is always expanding.

He writes:

The mass density of the universe is finely balanced to permit life to a degree of one part in 10^59. If the universe were slightly more massive, an overabundance of deuterium from the big bang would cause stars to burn too rapidly for the formation of complex life. If the universe were slightly less massive, an insufficiency of helium would result in a shortage of the heavy elements — again, resulting in no life.

The density of protons and neutrons in the cosmos relates to the cosmic mass density. That density determines just how much hydrogen fuses into heavier elements during the first few moments after the origin of the universe. In turn, the amount of heavier elements determines how much additional heavy-element production occurs later in the nuclear furnaces or stars.

What would be the consequence if the respective density of neutrons and protons were significantly lower? Firstly, nuclear fusion would occur with less efficiency. Consequently, the heavier elements such as carbon, nitrogen, oxygen, phosphorous, sodium and potassium — all of which are essential for the emergence of physical life — would not be formed. Moreover, assuming no additional cosmic density factors such as dark energy, a cosmos which possesses less mass density would prohibit the formation of stars and planets. Why? The expansion rate would be so big that matter would expand too quickly for gravity to pull together the gas and dust to allow their formation. If that were not enough, with only a little extra mass, the cosmos would expand so slowly that all stars in the cosmos would quickly turn into black holes and neutron stars. The density near the surface of such bodies would be so enormous that molecules would be impossible. Therefore, life would not be possible. The radiation from the formed black holes and neutron stars would also render physical life an impossibility at any point in a universe with such a high density.

Conversely, what would be the effect if the density of protons and neutrons in the cosmos were to be significantly higher? Nuclear fusion would be too productive, meaning that all the hydrogen in the universe would rapidly fuse into elements heavier than iron. The ultimate result is the same — the life-essential elements would not exist. Moreover, if the cosmic mass density were to be greater, gas and dust would condense so effectively under gravity’s influence that all stars would be much more massive than the Sun. Thus, planets would not be life-permitting because of the intensity of the radiation of their respective star, and additionally because of the rapid changes in the stars’ temperature and radiation.

The mass of the universe exhibits cosmic fine tuning to simultaneously permit two features which are essential for permitting life: (1) the correct diversity and quantity of elements; and (2) the appropriate rate of cosmic expansion required to allow life. Such cosmic fine-tuning bespeaks foresight and planning — indicators of intelligent design.
