Episode notes

The big bang is an event that we reconstructed as probably happening in the past of our universe based on current observational data. So I think it makes sense to talk about where you are locally. What could exist outside the universe? They become part of our reasoning and therefore part of our causal chain of things that we can do. The multiverse exists, but it doesn't exist as a multiverse of possible universes. It exists as an idea in our minds that allows us to reason about how physics works,. And then to do physics differently because we've reason about it that way.

Sara Walker is an astrobiologist and theoretical physicist. Lee Cronin is a chemist. This is a conversation and debate about alien life and alien civilizations. Please support this podcast by checking out our sponsors:
