Wolfram's "grid cell" concept is based on cellular automata (similar to Game of Life), where each cell has simple rules that, when taken together, add up to complex overall behavior (emergent phenomena).

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.
