#433 โ€“ Sara Walker: Physics of Life, Time, Complexity, and Aliens

Right. So, well, I think there's sort of two questions embedded here. I think the one that we can't answer by answering life is why certain things exist and others don't. But I think the sort of ultimate question, the sort of like prime mover question of why anything exists, we will not be able to answer.

Oh, there's nothing outside the universe. So I have a very โ€“ I am a very โ€“ like I am like the most physicalist that like anyone could be. So like for me, everything exists in our universe. And like I like to like think it like everything exists here. So even when we talk about the multiverse, I don't โ€“ like to me, it's not like there's all these other universes outside of our universe that exist.

The multiverse is a concept that exists in human minds. And it allows us to have some counterfactual reasoning to reason about our own cosmology, and therefore it's causal in our biosphere to understanding the reality that we live in and building better theories. But I don't think that the multiverse is something... And also math.

I don't think there's a platonic world that mathematical things live in. I think mathematical things are here on this planet. I don't think it makes sense to talk about things that exist outside of the universe. If you're talking about them, you're already talking about something that exists inside the universe and is part of the universe and is part of what the universe is building.

And you can say that, and that's an interesting philosophy. But again, this is sort of like pushing on the boundaries of the way that we understand things. I think it's more constructive to say the fact that I can talk about those things is telling me something about the structure of where I actually live and where I exist.

Well, it may not be true. It may be something that allows me to build better theories I can test to try to understand something objective.
