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

Yeah. But, yeah, I mean, that's consistent with many worlds, right? Because, like, there's this constant branching. But it doesn't really have a directionality to it. I don't know. Many worlds is weird.

So my interpretation of reality is, like, if you folded up, like, all that bifurcation of many worlds and you just fold it into the structure that is you and you just said you are all of those many worlds โ€“ And, like, that sort of, you know, like, your history, like, converged on you. But, like, you're actually an object exists that's, like, that, you know, was selected to exist.

And you're self-consistent with the other structures. So, like, the quantum mechanical reality is not the one that you live in. It's this very deterministic classical world. And you're carving a path through that space. But I don't think... that you're constantly branching into new spaces. I think you are that space.

No, it's random at the bottom, right? But like this randomness that we see at the bottom of reality that is quantum mechanics, I think like people have assumed that that is reality. And what I'm saying is like all those things you see in many worlds, all those versions of you, just collect them up and bundle them up. And like, they're all you. And what has happened is,

You know, like elementary particles don't have, they don't live in a deterministic universe, the things that we study in quantum experiments. They live in this fuzzy random space. But as that structure collapsed and started to build structures that were deterministic and evolved into you, you are a very deterministic macroscopic object.

And you can look down on that universe that doesn't have time in it, that random structure. And you can see that all of these possibilities look possible, but they're not possible for you because you're constrained by this giant causal structural history. So you can't live in all those universes.

You'd have to go all the way back to the very beginning of the universe and retrace everything again to be a different you.
