What is the fine-tuning argument for God’s existence, and does the multiverse counter it?

One of the best arguments for the existence of a Creator and Designer of the universe is the cosmic fine-tuning argument. The argument argues that individual constants and quantities in nature cannot be much smaller or larger than they are, because it would remove the ability of the universe to support life of any kind. Dr. Michael Strauss, an experimental physicist, explains some examples of the fine-tuning in a recent post on his blog.

He writes:

I liken the finely-tuned universe to a panel that controls the parameters of the universe with about 100 knobs that can be set to certain values. If you turn any knob just a little to the right or to the left the result is either a universe that is inhospitable to life or no universe at all.

Consider the knob that controls the strength of the strong nuclear force that holds quarks inside the neutrons and protons and binds the nucleus of the atom together. If the strength were increased by 2%, the element hydrogen would be either non-existent or very rare. Without hydrogen there would be no water (H2O) or stars that burn hydrogen as their nuclear fuel like our sun.  Without hydrogen there would be no life. If the strength of the strong nuclear force were decreased by about 5%, then hydrogen would be the only element in the universe. That would simplify the periodic table and make Chemistry class very easy, but it would render life impossible.

All known life in this universe is based on the element carbon, which is formed in the final stages of a star’s life. The carbon you and I are made of is the result of the nuclear processes that occurred as previous stars ended their lives. One nice recent study showed that if the mass of the quarks that make up neutrons and protons were changed by just a few percent, then the process that makes carbon as stars die would be altered in such a way that there would not be sufficient carbon in the universe for life. The masses of the lightest sub-atomic quarks are the precise value that is required for carbon to form and for life to exist.

Regarding the multiverse, let me just quote from MIT physicist Alan Lightman, writing in Harper’s magazine about the multiverse:

The… conjecture that there are many other worlds… [T]here is no way they can prove this conjecture. That same uncertainty disturbs many physicists who are adjusting to the idea of the multiverse. Not only must we accept that basic properties of our universe are accidental and uncalculable. In addition, we must believe in the existence of many other universes. But we have no conceivable way of observing these other universes and cannot prove their existence. Thus, to explain what we see in the world and in our mental deductions, we must believe in what we cannot prove.

Sound familiar? Theologians are accustomed to taking some beliefs on faith. Scientists are not. All we can do is hope that the same theories that predict the multiverse also produce many other predictions that we can test here in our own universe. But the other universes themselves will almost certainly remain a conjecture.

The multiverse is not pure nonsense, it is theoretically possible.But even if there were a multiverse, the generator that makes the universes itself would require fine-tuning, so the multiverse doesn’t get rid of the problem. And, as Lightman indicates, we have no independent experimental evidence for the existence of the multiverse in any case. Atheists just have to take it on faith, and hope that their speculations will be proved right. Meanwhile, the fine-tuning is just as easily explained by postulating God, and we have independent evidence for God’s existence, like the the origin of biological information, the sudden appearance of animal body plans, the argument from consciousness, and so on. Even if the naturalists could explain the fine-tuning, they would still have a lot of explaining to do. Theism (intelligent causation) is the simplest explanation for all of the things we learn from the progress of science.

It’s very important to understand that if these values were any different, then it’s not like we would bridges on our foreheads, or have green skin, or have pointy ears, etc. That’s what science fiction teaches you. And many atheists form their view of science by watching science fiction entertainment. But the truth is that the consequences of changing these values are much more consequential: no stars, no planets, no hydrogen, no heavy elements, the universe re-collapses into a hot fireball. You’re not going to have complex, embodied intelligent agents running around making moral decisions and relating to God in a world like that.

Questions like the existence of God should be NOT decided by feelings and faith and superstitious nonsense. They ought to be decided by evidence. Specifically, scientific evidence. Everyone has to account for this scientific evidence for fine-tuning within their worldview, and they have to account for it in a way that is responsible and rational. Punting to the multiverse, without any evidence for it, is neither rational nor responsible. Holding out hope that the evidence we have now will all go away is neither rational nor responsible.

By the way, if you are looking for a good book on the cosmic fine-tuning, especially for evangelism and debating with atheists, you really need to get a copy of “A Fortunate Universe“. Although it is from one of the most prestigious academic presses, it is pretty funny to read, and the main points are made clearly, even if you don’t understand the science. Two astrophysicists wrote it – one who believes that God is the best explanation of the fine-tuning, and one who doesn’t. I really think that Christians need to get used to the idea that evangelism can be pretty easy, so long as you are arguing from peer-reviewed facts. When you get a good book on evidence for God that is not in dispute, then you are invincible. Everybody ought to believe in God in a universe with this much overt scientific evidence spilling out everywhere. Whether this Creator and Designer is the God of the Bible, who visited us as Jesus of Nazareth, takes more work to establish. Working through the emotional objections people have to God, and coaching them to take on the difficulties of living out a authentic Christian life (very unpopular!), is even harder.

Making sense of evil and suffering within a Christian worldview

5 Comments

One thing I’ve noticed in talking to atheists who grew up in Christian homes is that they often leave their Christian worldview behind because of a disappointment with God. For some reason, they get this idea that God is our cosmic butler. We can do whatever we want in order to be happy, and if we want any help in this, then we just ring for him. When we encounter disappointment, our tendency is to just leave God behind.

Paul Copan explains the high points of the problems of evil and suffering in 17 minutes. (H/T Apologetics 315)

The MP3 file is here.

The video is here:

Topics:

  • the question itself reveals that we are moral beings
  • the problem of evil is the great interrupter of human well-being
  • every philosophy of life has to address this question
  • is God required to give us a life that is easy and comfortable?
  • evil is a departure from good, i.e. – the way things ought to be
  • a way things ought to be implies a plan for what ought to be
  • human evil implies a plan for the way we ought to be
  • free creatures have the ability to deviate from the plan
  • where does this plan for the universe and us come from?
  • how can there be a way we ought to be come from?
  • evil is the flip side of good so where does good come from?
  • God’s own moral nature is the standard of good and evil
  • where does evil from natural disasters come from?
  • how dangerous natural phenomena preserve Earth’s habitability
  • there is a benefit from tectonic activity
  • similarly, God lets humans freely choose knowing harm may result
  • people are free to try to find meaning in something other than God
  • God is able to use negative things to bring about positive results
  • e.g. – when good people suffer, they can comfort and care for others
  • can people be good enough on their own without God?

I do think it’s worth thinking about whether the New Testament portrays God as our cosmic butler, just waiting on us hand and foot so that we can be happy. Personally, I think you’d have to be crazy to get that impression of God from the Bible. Especially from the life of Jesus, who suffers in order to do the will of his Father. Wouldn’t it be funny if atheists were disbelieving in a God of their own making? Suffering in the pursuit of goodness has always been the center of the Christian life. I’m not sure where people get this idea that God’s job is to make us happy, according to our own desires. Seems kind of shallow. Certainly not Biblical. Do people even read the Bible any more to find out what God is really like? Maybe that’s the problem.

If you want to read two good books for beginners on Christian Apologetics that cover a range of intermediate issues, then pick up “Passion Conviction” and the companion “Contending With Christianity’s Critics”. Awesome, awesome resources. The Kindle editions can often be had for $3 each on Amazon.

William Lane Craig lectures on the moral argument at Georgia Tech

Making sense of the meaning of atheism

This video has 3 parts, as well as questions and answers in individual clips.

For those who cannot watch the video, you can read this essay by Dr. Craig which covers exactly the same ground as the video. The essay is for Christians already familiar with basic apologetics.

Part 1 of 3:

Part 2 of 3:

Part 2 of 3:

Here’s a quick couple of quotes from the essay for those who cannot watch:

If there is no God, then any ground for regarding the herd morality evolved by homo sapiens as objectively true seems to have been removed. After all, what is so special about human beings? They are just accidental by-products of nature which have evolved relatively recently on an infinitesimal speck of dust lost somewhere in a hostile and mindless universe and which are doomed to perish individually and collectively in a relatively short time. Some action, say, incest, may not be biologically or socially advantageous and so in the course of human evolution has become taboo; but there is on the atheistic view nothing really wrong about committing incest. If, as Kurtz states, “The moral principles that govern our behavior are rooted in habit and custom, feeling and fashion,”5 then the non-conformist who chooses to flout the herd morality is doing nothing more serious than acting unfashionably.

The objective worthlessness of human beings on a naturalistic world view is underscored by two implications of that world view: materialism and determinism. Naturalists are typically materialists or physicalists, who regard man as a purely animal organism. But if man has no immaterial aspect to his being (call it soul or mind or what have you), then he is not qualitatively different from other animal species. For him to regard human morality as objective is to fall into the trap of specie-ism. On a materialistic anthropology there is no reason to think that human beings are objectively more valuable than rats. Secondly, if there is no mind distinct from the brain, then everything we think and do is determined by the input of our five senses and our genetic make-up. There is no personal agent who freely decides to do something. But without freedom, none of our choices is morally significant. They are like the jerks of a puppet’s limbs, controlled by the strings of sensory input and physical constitution. And what moral value does a puppet or its movements have?

[…]Moreover, if atheism is true, there is no moral accountability for one’s actions. Even if there were objective moral values and duties under naturalism, they are irrelevant because there is no moral accountability. If life ends at the grave, it makes no difference whether one lives as a Stalin or as a saint. As the Russian writer Fyodor Dostoyevsky rightly said: “If there is no immortality, then all things are permitted.”

If you want a much shorter, slicker version of this argument to share, Reasonable Faith has produced this nice 5-minute video that you can tweet or share on your Facebook page or whatever:

The moral argument is the easiest argument in the world to discuss with non-Christians, as everyone has to have an answer to questions like “what makes humans valuable?” and “why should I do the right thing when it goes against my self-interest?” and “will evildoers who escape justice in this life be punished when they die?” and “do humans have free will to make moral choices?” These are interesting questions, and people can just give their opinion and then think about it as they discuss it.

If you want to show this lecture and Q&A to your apologetics group, you can find the DVD here.

You can also read a debate transcript where Dr. Craig puts his ideas to the test, against Dr. Richard Taylor. I found this debate very helpful for answering the question that everyone should be able to answer: “why should I be moral?”
