What is time? Time is a computational phenomenon. Time is the progressive change of the network. One particle touches another one, touches another one, this thing changes this one, this changes this one. Sounds to me like you're describing your cellular automata. Yes, it's very much like that. It's a computational process.

And it happens to be operating on these hypergraphs rather than just lines of black and white cells. So the universe itself is a computer... - Yes. ...running a computational exercise. Yes, well, I don't know whether you'd call it an exercise, but... It is computing. - Yes, it is computing.

And that's what the progress of time is. And time is the progress of that computation. - Yes. And that is what people mean when they say, "Are we living in a simulation?" No. (MUSIC) you
