#404 – Lee Cronin: Controversial Nature Paper on Evolution of Life and Universe

Because the nice thing is if, when you do compression in computer science, we're wandering a bit here, but it's kind of worth wondering, I think in you, you, um, assume you have instantaneous access to all the information in the memory. Yeah. In assembly theory, you say, no, you don't get access to that memory until you've done the work.

And then when you don't access that memory, you can have access, but not to the next one. And this is how in assembly theory, we talk about the four universes, the assembly universe, the assembly possible, and the assembly contingent, and then the assembly observed. And they're all scales in this combinatorial universe.

Yep, so the assembly universe is like anything goes. It's just combinatorial kind of explosion in everything. So that's the biggest one? That's the biggest one. It's massive.

So, yeah, so assembly universe, everything goes. Yep. Assembly possible, laws of physics come in, in this case in chemistry bonds. In assembly, so that means... Those are actually constraints, I guess. Yes. And they're the only constraints. They're the constraints of the base. So the way to look at it, you've got all your atoms, they're quantized, you can just bung them together.

So then you can become a kind of... So in the way in computer science speak, I suppose the assembly universe is just like no laws of physics. Things can fly through mountains beyond the speed of light. In the assembly possible, you have to apply the laws of physics, but... you can get access to all the motifs instantaneously with no effort. So that means you could make anything.

Then the assembly contingent says, no, you can't have access to the highly assembled object in the future until you've done the work in the past on the causal chain. And that's really the really interesting shift where you go from assembly possible to assembly contingent. That is really the key thing in assembly theory that says you cannot just have instantaneous access to all those memories.
