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

MIT physicist Alan Lightman on fine-tuning and the multiverse

Here’s the article from Harper’s magazine. The MIT physicist says that the fine-tuning is real, and is best explained by positing the existence of an infinite number of universes that are not fine-tuned – the so-called multiverse. Excerpt: While challenging the Platonic dream of theoretical physicists, the multiverse idea does explain one aspect of our universe … Continue reading MIT physicist Alan Lightman on fine-tuning and the multiverse

What are Boltzmann brains, and what challenge do they pose to the multiverse hypothesis?

I thought I would turn to the atheist theoretical physicist Sean Carroll, who has previously debated William Lane Craig, to explain to us what a Boltzmann brain is, and what threat it posts to the multiverse hypothesis. Here is Sean Caroll, quoted by About.com: Ludwig Boltzmann was one of the founders of the field of … Continue reading What are Boltzmann brains, and what challenge do they pose to the multiverse hypothesis?
