#433 – Sara Walker: Physics of Life, Time, Complexity, and Aliens

I think it's the fact that it's open-ended in some sense. It's another open-ended combinatorial space and the recursive properties of it allow creativity to happen. which is what you see with the revolution in the last century with GΓΆdel's theorem and Turing. And there's clear places where mathematics notices holes in the universe.

Definitely not chemical. I mean, chemistry is one substrate.

And I think Darwinian evolution is a problem, but the reason that that definition is a problem is not because evolution is in the definition, but because the implication is that evolution you know, that most people would want to make is that an individual is alive.

And the evolutionary process, at least the Darwinian evolutionary process, most evolutionary processes, they don't happen at the level of individuals. They happen at the level of populations. So again, you would be saying something like what we saw with the self-sustaining definition, which is that populations are alive, but individuals aren't because populations evolve and individuals don't.

And obviously, maybe you're alive because your gut microbiome is evolving, but Lex as an entity right now is not evolving by canonical theories of evolution. In assembly theory, which is attempting to explain life, evolution is a much broader thing. So

Yes. You're constructing yourself all the time. Assembly theory is about construction and how the universe selects for things to exist.
