Episode Details

An atheist response to fine-tuning: a super intellect ‘monkeying’ with the physics, a cosmic computer simulation, the multiverse hypothesis, and “the Gambler’s Fallacy.”

So far, we’ve heard from five different university-trained scholars with theistic worldviews about fine-tuning of the universe: a Christian astronomer, a Jewish mathematician/physicist duo, a Christian astrophysicist, and a Christian theologian/philosopher. In this episode, we’ll hear from another university-trained astrophysicist on the same subject, but this one describing himself as a card-carrying atheist … and who nonetheless agrees that the data strongly suggests the universe is indeed fine-tuned. Dr. Geraint Lewis grew up in Wales, was a science junky from the time he could first read, who later found he was good with mathematics and physics, and eventually found himself as a Professor of Astrophysics at the Sydney Institute for Astronomy. And he firmly accepts fine-tuning … but without a “Tuner”!?

We first checked if he means something different than our other five guests, when he refers to “fine-tuning.” He too points to the fundamental constants of the universe: he agrees that scientists have discovered equations which explain various aspects of the universe, through a process of contemplation, reasoning and scratching away on chalkboards, but those equations have certain constants that can’t be derived in any way …. they just have to be measured. 

For example, almost everyone has heard of Einstein’s famous equation: E=mc².  Reasoning alone drives him (and them) to two conclusions: that energy and matter are interchangeable (we said
