The Fine-Tuning Argument for God’s Existence, Part Two

“The Closet Atheist” has received several comments about her recent post on fine-tuning. The basic idea is that the laws of our universe might have been quite different from the way they actually are. But if they had been even a tiny bit different, life as we know it could never have existed. So perhaps the cosmos was carefully designed as a home for living creatures, including humans. That implies a designer – a god.

This theory is actually controversial, and the Closet Atheist herself rejects it. But a fellow named Zane replied: “I’m not a physicist, … but I think there are better motivations for positing a multiverse than the fine-tuning problem …”

Zane points out that there are several different concepts of the multiverse. For example, if the universe is infinite, “everything possible is bound to happen,” so … “there are regions within that space that will never influence one another, making them functionally separate universes.”

In addition, a many-universes theory might help explain “some of the weirdness in quantum mechanics.” Some interpretations of quantum theory suggest that every single instant gives birth to a great many futures. “So at each point where multiple things could happen, everything possible thing happens, resulting in an infinite budding of minutely differing universes.”

Question: Why would the manifold futures that are perhaps implied by quantum theory result in futures with new sets of fundamental laws? Any comments?

Next time I’ll mention some ideas about the multiverse from my book, Bridging the God Gap.

The Fine-Tuning Argument for God’s Existence, Part One

A while back on this web site I posted a series in which I debated with myself about the existence of God. “Pastor Chris” and “Dr. Schriner” argued about various aspects of this topic, including the claim that the laws of the universe are fine-tuned for intelligent life. Continue reading
