Suppose you and I depart from point A simultaneously. We both travel in spaceships to point B and arrive there at the same time. We both took round-a-bout paths, but you travelled at relativistic speeds and I went much slower. The clock on your ship shows less elapsed time than mine. You didn't slow your clock or something, your time-distance through space/time was actually shorter than mine. That is... very weird. We were both at co-ordinates (Ax, Ay, Az, At) and (Bx, By, Bz, Bt), but Bt - At is larger for me than for you. We can't agree on what the co-ordinate values are or how much they differ. I don't think a simple cell grid is going to capture that. Entanglement is also deeply weird. I'm not a physicist, but believe it works this way: Particles A and B are entangled. Later, particles A and C become entangled. That doesn't mean that A and B are no longer entangled. Schroedinger's Cat becomes entangled with the particle which does/doesn't decay. When I open the box I become, in a very complex way, entangled with the Cat. Either it is dead and I become depressed, or it is alive and I start looking for milk. But the Cat and the particle are still entangled. If someone, unaware of my existence, later measures the particle they will absolutely know the state of the Cat. Or they could measure me; if I'm hunting for milk then the particle state is "didn't decay." Eventually, everything becomes entangled with everything else. How is that kept track of? How massive (literally) would that amount of information be? |

Following it further:
The speed of light is due to the refresh rate of these cells. The passage of time (and relationship b/t it and velocity), is because of computational limits on those cells. A cell has limited processing power that can either be spent on updates (the passage of time) or I/O (velocity). Objects also appear to shrink when moving at relativistic speeds, right? Another computational optimization, smaller means less cells are used.
It's a pretty neat mapping. A spaceship is moving at relativistic speeds, which has a large I/O cost on the cells it exists in. That cost is made up in different ways, depending if you're inside or outside the spaceship.
On the inside:
time moves slower, saving time cycles for I/O cycles
On the outside:
the spaceship physically shrinks, using less cells total

Not too sure about entanglement, but I believe it's tied to eventual consistency. You have the direction backwards though, yeah? The point of Schoedingers cat is that while it's in the box, it may as well not exist. Everything being entangled is just the regular universe.
