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

Oh, I see. And so you're actually like, when you have this splitting of making a molecule that now has another form it could have had by the same exact atomic composition, but now it's just a mirror image isometry, you're basically splitting the universe of possibilities every time.

In two, but molecules can have more than one chiral center, and that's not the only stereosometry that they can have. So This is one of the reasons that Toxol fills 1.5 universes It's all of these spatial permutations that you do on these objects that actually makes the space so huge.

So the point of this sort of chiral transition that I'm putting out is chirality is actually a signature of being in a complex chemical space. And the fact that we think it's a really generic feature of chemistry and it's really prevalent is because most of the chemistry we study on Earth is a product already of life.

And it also has to do with this transition in assembly, this transition in possibility spaces. Because I think there's something really fundamental going on at this boundary that you don't really need to go that far into chemical space to actually see life in terms of this depth in time, this depth in symmetries of objects in terms of like chiral symmetries or this assembly structure.

But getting past this boundary that's not very deep in that space requires life. It's a really weird property, and it's really weird that so many abrupt things happen in chemistry at that same scale.

Well, it's efficient for things to eat other things that are already alive because they don't have to go all the way back to the, Base chemistry.
