The assumption seems to be that the purpose of the simulation is to investigate humans. In that case, why bother to simulate the entire Universe?

Right. And why so much unnecessary detail down to the quark level?

(Of course, if you really like the simulation idea, maybe we're in an unimportant corner of the simulation and the real action being observed is elsewhere. Much simulation-hypothesis blithering has the same human-centered problem as theology.)

Floating point has a finite resolution, and so does the position of subatomic entities, it turns out. I'm sure it's just a coincidence. :)

No, floating point would result in physics behaving differently depending on distance from the origin, which is a problem with some game physics engines.

(More promising was Wolfram's attempt to define physics in terms of cellular automata, which does not seem to have worked out.)
