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

And then you only see molecules that, you know, the only molecules that we observe that are past that threshold are ones that are in life. And in fact, one of the things I'm trying to do with this idea of like trying to actually quantify the origin of life as a transition is in like a phase transition assembly theory is actually be able to explain why that boundary is where it is.

Because I think that's actually the boundary that life must cross. So the idea of going back to this thing we were talking about before about these structures that can reinforce their own existence and move past that boundary, 15 seems to be that boundary in chemical space. It's not a universal number. It will be different for different assembly spaces.

Recursive. Yeah. So you can think of objects in assembly theory as basically recursive stacks of the construction steps to build them. So they're like, it's like you take this step and then you make this object and you make it this object and make this object and then you get up to the final object. But that object is all of that history rolled up into the current structure.
