Biologist Richard Dawkins, in his book, The Blind Watchmaker, wrote the following:

The theory of evolution by cumulative natural selection is the only theory we know of that is, in principle, capable of explaining the existence of organized complexity. Even if the evidence did not favour it, it would still be the best theory available.

In this episode, we discuss physicist Lee Smolin's attempt to extend natural selection from biology and apply it to the cosmos as a whole in order to explain fine tuning in physics. We start by discussing black holes and baby universes and end with what Smolin calls the meta-laws dilemma.
