The Fine-Tuning of the Multiverse Audio Lecture

by Max Andrews

In honor of today’s lecture on fine-tuning and the multiverse I recorded the lecture and I’m posting it online here. I hope you enjoy it and make good use of it.

Audio lecture from 18 October 2012.

The fine-tuning argument argues that when the physics and the laws of nature are expressed mathematically their values are ever so balanced in a way that permits the existence of life.  This claim is made on the basis that existence of vital substances such as carbon, and the properties of objects such as stable long-lived stars, depend rather sensitively on the values of certain physical parameters, and on the cosmological initial conditions.[1]  I’m merely arguing that the universe/multiverse is fine-tuned for the essential building blocks and environments that life requires for cosmic and biological evolution to even occur.

  1. Given the fine-tuning evidence, a life permitting universe/multiverse (LPM) is very, very epistemically unlikely under the non-existence of a fine-tuner (~FT): that is, P(LPM|~FT & k’) ≪ 1.
  2. Given the fine-tuning evidence, LPM is not unlikely under FT (Fine-Tuner): that is, ~P(LPM|FT & k’) ≪ 1.
  3. Therefore, LPM strongly supports FT over ~FT. [2]

*Remember, k’ represents some appropriately chosen background information that does not include other arguments for the existence of God while merely k would encompass all background information, which would include the other arguments, and ≪ represents much, much less than (thus, making P(LPM|~FT & k’) close to zero).
