The production of carbon from lighter elements is fine-tuned to an amazing degree

Fine-tuning of the strong nuclear force and the fine structure constant
Fine-tuning of the strong nuclear force and the fine structure constant

If there is one thing that science fiction is good for, it’s for popularizing the phrase “carbon-based life”. Everyone has heard that carbon is essential for life. But do you know why carbon is so important? And did you know that the reaction that produced the carbon in our universe is actually fine-tuned, and therefore evidence for a Creator and Designer of the universe?

Hugh Ross has a new article up in Salvo magazine, which I found thanks to a post at Uncommon Descent.

Now he starts off with a discussion of how the mass density of the universe needed to be fine-tuned in order to produce elements heavier than hydrogen from the (only) hydrogen that was present at the creation event. I’ve talked about that reaction previously, but I won’t repeat that here. Nucleosynthesis is one of the most important chemical reactions in science, and something every Christian should know and understand well enough to explain it.

You can’t make complex embodied intelligent creatures such as ourselves out of only hydrogen and helium, but you can’t make a life permitting universe without some hydrogen and helium. For one thing, you can’t have liquid water without some hydrogen.

But the element carbon is the center hub of all of the molecules inside of us that allow for the storage and processing of information necessary for life.  And it turns out that the reaction that creates carbon from elements lighter than carbon is fine-tuned to an amazing degree.

Excerpt:

But cosmic mass density is not the only thing that must have been exquisitely fine-tuned for the universe to contain any carbon. The nuclear resonance (or energy) levels for helium, beryllium, carbon, and oxygen also had to be exquisitely fine-tuned for carbon to exist. Here’s how that happens.

Stars fuse carbon and oxygen from helium through a series of reactions known as the triple-alpha process, in which three helium nuclei are combined to make one carbon nucleus. In the first step in this process, two helium nuclei (with 2 protons each) fuse together to make beryllium (which has 4 protons). Next, a helium nucleus fuses with a beryllium nucleus to make carbon (which has 6 protons). Then, some carbon nuclei fuse with helium nuclei to make oxygen (which has 8 protons).

The only reason that the triple-alpha process produces any carbon or oxygen at all is because in the first step, the ground state energy level (i.e., the state of an atom when all of its electrons are at their lowest energy levels) of the beryllium-8 nucleus (containing 4 protons and 4 neutrons) almost exactly equals the ground state energy level of two helium-4 nuclei (2 protons and 2 neutrons each). In the second step, the ground state energy level of a beryllium-8 nucleus plus a helium-4 nucleus almost exactly equals the energy level of an excited state of a carbon-12 nucleus (6 protons and 6 neutrons). In the third step, the ground state energy level of a carbon-12 nucleus at 7.65 million electron volts is just slightly larger than the ground state energy level of an oxygen-16 nucleus (8 protons and 8 neutrons) at 7.12 million electron volts.1

If it were not for the near equivalences or resonances of the nuclear energy levels of two helium nuclei relative to a beryllium nucleus, and of a beryllium nucleus plus a helium nucleus relative to a carbon nucleus, the universe would contain very little or no carbon and very little or no elements heavier than carbon. Life would be impossible.

Furthermore, unless the difference in the nuclear energy levels between a carbon nucleus and an oxygen nucleus were precisely 0.53 million electron volts, the universe would contain either a lot of carbon and no oxygen or a lot of oxygen and no carbon. Either way, physical life would be impossible in the universe.

In the early 1950s, astronomer Fred Hoyle and physicist Willy Fowler were the first to understand how critical the relative nuclear energy levels of helium, beryllium, carbon, and oxygen were for making life possible in the universe. Commenting on the highly fine-tuned nature of these nuclear energy levels, Hoyle wrote in an article he published in Engineering & Science,

A common sense interpretation of the facts suggests that a superintellect has monkeyed with the 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 beyond question.2

The article continues to explain that there is an additional problem of carbon fine-tuning related to habitability.

The carbon formation problem is one of the best examples of fine-tuning, and as you can see, it’s even admitted by atheists. It’s not the easiest one to explain (because resonance levels are not familiar in every day life), but it’s worth knowing about all three of the fine-tuning topics in the post.

Keep in mind that the more science has made progress, the more fine-tuning problems we have discovered. The trend is very bad if you are a naturalist. But very good if you are a theist. Evidence matters, and scientific evidence is the best kind of evidence.

Yes, William Lane Craig debate transcripts. In fact, I still read them from time to time to keep up my skills.

Here’s one of my favorites, the Craig-Nielsen debate on grounding morality without God

Summary:

THE CRAIG-NIELSEN DEBATE: GOD, MORALITY, AND EVIL
William Lane Craig and Kai Nielsen
with annotations by William Lane Craig
February 1991, University of Western Ontario

Best part:

Finally, he raises the issue of immortality and says, “Death doesn’t undermine moral values. In fact, things that we value become all the more precious.” Well, in one sense he’s right. It’s the absence of God that undermines the objectivity of moral values, not death. But let’s suppose that there are objective moral values. What would be undermined by the lack of immortality? I think two things.

First, I think there would be no reason to adopt the moral point of view. Since you’re going to die, everyone ends up the same. It doesn’t make any difference whether you live as a Hitler or a Mother Teresa. There is no relationship between your moral living and your ultimate fate. And so in that sense, death undermines the reason for adopting the moral point of view rather that just being an egoist and living for self.

Second, there’s no basis for self-sacrifice on this point of view. Why should an atheist, who knows everything is going to end in death, do things that are morally right that go against self-interest? For example, a few years ago there was a terrible mid-winter air disaster in Washington, DC, as a plane crashed into a bridge spanning the Potomac River, spilling its passengers into the icy waters. And as the helicopters came to rescue these people, attention focused on one man who again and again passed by the rope ladder rather than be pulled to safety himself. Seven times he did this, and when they came again, he was gone. The whole nation turned its eyes to this man in respect and admiration for the noble act of self-sacrifice that he did. And yet on the atheistic view, that man wasn’t noble. He did the stupidest thing possible. He should have gone for the rope ladder first, pushed others away, if necessary, in order to survive! But to give up all the brief existence he will ever have for others he didn’t even know? Why? It seems to me, then, that it’s not simply the absence of God that undermines objective moral values, but ethical living is also undermined by the atheistic point of view because you then have no reason to adopt the moral point of view and you have no basis for acts of self-sacrifice.

By contrast, on the Christian view, where you have both God and immortality, you have the necessary presuppositions for the affirmation of objective moral values and for consistent living of the ethical life.

And another of my favorites, the Craig-Taylor debate on the ontological grounding of morality.

Summary:

Is The Basis Of Morality Natural Or Supernatural?
Richard Taylor and William Lane Craig
October 1993, Union College, Schenectady, New York

Sample Craig:

(2) I argued that moral accountability also exists under the supernaturalist view, and Professor Taylor didn’t deny the point.

(II) What about my critique, then, of naturalism? I said that naturalism doesn’t provide a sound foundation for morality, and here I made two points:

(1) On the naturalist view, objective right and wrong do not exist. Again, Professor Taylor doesn’t deny this point; he just says, “Well, to say that they’re conventional doesn’t mean they’re contemptible.” Well, granted; but it does mean they’re arbitrary, they’re non–objective. There’s no more difference between moral right and wrong than driving on the right–hand side of the road versus the left–hand side of the road. It’s simply a societal convention. And the modern evolutionist thinks these conventions are just based in socio–biological evolution. According to Michael Ruse, a professor of the philosophy of science,

The position of the modern evolutionist…is that humans have an awareness of morality…because such an awareness is of biological worth. Morality is a biological adaptation, no less than are hands and feet and teeth…. Considered as a rationally justifiable set of claims about an objective something, [ethics] is illusory. I appreciate that when somebody says, ‘Love thy neighbor as thyself,’ they think they are referring above and beyond themselves…. Nevertheless…such reference is truly without foundation. Morality is just an aid to survival and reproduction and…any deeper meaning is illusory….{26}

This is essentially the same view as Professor Taylor’s. Moral values are simply rooted in socio–biological evolution, that have passed down as certain taboos and certain commands, but they have no objective validity in terms of their moral rightness or wrongness. Professor Taylor says, “But I have a high regard for people who are truly moral and decent.” I don’t deny that. Of course he does! But the point is that in his ethics, in his philosophy, he has no basis for that affirmation. What I bring is not a new set of values—I think we pretty much hold those in common—but I’m offering a secure foundation for those values that we all want to hold dear.

You see, on Professor Taylor’s view, there really isn’t any objective morality. I think every one of us here tonight would agree that it’s wrong to kill babies and that the holocaust was morally wrong. But in his book Professor Taylor says, “The infanticide practiced by the Greeks of antiquity did not violate their customs. If we say it was nevertheless wrong, we are only saying that it is forbidden by our ethical and legal rules. And the abominations practiced by the Nazis…are forbidden by our rules, and not, obviously, by theirs.”{27} I submit that that is simply a patently false view of moral values and that naturalism, therefore, can’t provide any objective basis for right and wrong.

And another of my favorites, the Craig-Tooley debate on the problem of evil.

Summary:

A Classic Debate on the Existence of God
Dr. William Lane Craig & Dr. Michael Tooley
November 1994, University of Colorado at Boulder

Sample Craig:

(2) Christian doctrines increase the probability of the coexistence of God and the evils in the world. Let me just mention a couple of these.

(i) On the Christian view, the purpose of life is not happiness as such in this life. Rather it is the knowledge of God—which will ultimately produce true and everlasting happiness. What that means is that many evils occur in this life which might be utterly pointless with respect to producing human happiness. But they might not be pointless with respect to producing the knowledge of God. Dr. Tooley assumes when he talks about changes that would make this world a better place, that the purpose of life is basically to be happy in this life. And I certainly admit that you could make changes that might appear to make this life a better place, make it happier. But that’s not God’s purpose. So if you understand that the purpose of life is not happiness as such, I think that you can see that the existence of evil doesn’t necessarily cast any improbability upon God’s existence.

(ii) It’s also the Christian view that God’s purpose spills over into eternal life. In the afterlife God will bestow a glory and happiness upon us that is incomparable to what we’ve suffered here on earth. And the longer we spend in eternity with Him, the more the sufferings in this life shrink by comparison to an infinitesimal instant. Dr. Tooley admits in his article that it is possible that immortality could justify such evils. But, he says, it’s “very unlikely” that there is life after death. Well, I have two comments. First, I’d like him to prove that it’s unlikely that there is life after death.{26} Second, I suggest that the resurrection of Jesus gives us grounds for hoping in life after death, and I’ve attempted to justify that historically. So given these Christian doctrines, I think you can see that the existence of God and evil is not so improbable after all.

[…]

(4) Finally, I think that there is actually an argument for God from evil. It would go like this:

(i) If God does not exist, objective moral values do not exist. If there is no God, moral values are either socio-biological by-products or just expressions of personal preference.

(ii) Evil exists. That’s the premise of the atheist. There is real evil in the world.

(iii) Therefore, objective values do exist. Some things are really wrong.

(iv) Therefore, God exists.

Thus the presence of evil in the world actually demonstrates God’s existence because in the absence of God, there wouldn’t be any distinction objectively between good and evil, between right and wrong. So although evil in one sense calls into question God’s existence, in a much deeper sense, I think, it actually requires God’s existence.

So in the light of these four responses, I think that the argument from evil, as difficult and emotionally pressing as it might be, in the end doesn’t constitute a good argument against the existence of God. So I think the four arguments given against the existence of God by Dr. Tooley are inconclusive. You’ve still got my six arguments for God’s existence, and therefore I still think that on balance the evidence favors theism as the more rational worldview.

Stephen C. Meyer: does the Big Bang cosmology disprove the existence of God?

Christianity and the progress of science
Christianity and the progress of science

Here’s the 66-minute video featuring Dr. Stephen C. Meyer, who holds the Ph.D in philosophy of science from Cambridge University, and other degrees in the hard sciences.

The lecture starts really, really slowly. You can just fast-forward to the 12 minute mark, or you might die of boredom.

Topics:

  • Up until the the last 100 years or so, everyone agreed that the universe was eternal
  • This is at odds with the traditional Christian view that God created the universe
  • Materialism, the view that matter is all there is, requires eternally existing matter
  • Discovery #1: Hubble discovers that the universe is expanding (redshift observation)
  • The expanding universe was resisted by proponents of the eternal universe, like Einstein
  • Some naturalists even proposed speculative static models like the steady-state model
  • However, not of the speculative models fit with observations and experimental results
  • Discovery #2: Penzias and Wilson discover the cosmic microwave background radiation
  • Measurements of this background radiation confirmed a prediction of the Big Bang theory
  • The steady-state theory was falsified of by the discovery of this background radiation
  • The oscillating model was proposed to prevent the need for an absolute beginning
  • But the oscillating model is not eternal, it loses energy on each “bounce”
  • A paper by Alan Guth and Marc Sher from 1982 proved that our universe will not bounce
  • In addition, experiments reveal that the universe will expand forever, and not contract
  • The beginning of the universe is more at home in a theistic worldview than an atheistic one
  • The beginning of the universe fits in well with the Bible, e.g. – Genesis 1, Titus 1, etc.

In case you are wondering about what the evidence is for the Big Bang, here are 3 of the evidences that are most commonly offered:

Three main observational results over the past century led astronomers to become certain that the universe began with the big bang. First, they found out that the universe is expanding—meaning that the separations between galaxies are becoming larger and larger. This led them to deduce that everything used to be extremely close together before some kind of explosion. Second, the big bang perfectly explains the abundance of helium and other nuclei like deuterium (an isotope of hydrogen) in the universe. A hot, dense, and expanding environment at the beginning could produce these nuclei in the abundance we observe today. Third, astronomers could actually observe the cosmic background radiation—the afterglow of the explosion—from every direction in the universe. This last evidence so conclusively confirmed the theory of the universe’s beginning that Stephen Hawking said, “It is the discovery of the century, if not of all time.”

By the way, Dr. Meyer also does a great job of explaining the problem of proteins, DNA and the origin of life in this lecture. And you can hear him defend his views in this debate podcast with Keith Fox and in this debate podcast with Peter Atkins. He does a great job in these debates.
