In this case I'd say time is the constraint, as you want it to run consistently through your simulation. So you can't let one part get ahead or behind another in a way that breaks causality.
You are likely not running the universe on a Von Neumann machine, so compute and storage would be combined and spread out. You can't just have opposite ends of the universe interacting instantly in that case.
It doesn't have to be that way, but you can see why it would be desirable and seems to fit observations.
However, I'm at a loss how you would explain quantum entanglement if it truly is instant over any distance. That's not really known, but it's at least a lot faster than light.

- eloff 5y agoThis is true. The physics outside could be anything and we're unlikely to understand it. There's a chance us humans are simulating our past for some unknown reason - in which case one would expect the laws to be similar. It's also not unreasonable to think that there will be many similarities between the laws of the simulation and the outside reality because they'd have what they know to draw on for inspiration.

- karmakaze 5y agoMy point about time in a simulation is that it can be simulated. It's more a computation of a directed graph of causation. 'When' the computation happens in the host environment isn't material within the simulation. Trying to do things in any sort of 'to scale' time is an optimization rather than a requirement. I don't see the problem with entanglement at all unless it was so prevalent as to direct the shape of the simulation model. If it's a lesser exceptional quantity, they can be handled as special cases, whenever one is evaluated, the universe could even in the most crude implementation, be briefly stopped, the entangled partners updated, and resumed. Pretty much like running in a VM that's doing gc if your real time clock is arbitrary information provided by the host environment.
