The universe's developers argued over whether to have a speed limit to make it easier to parallelize, or to have reference frame invariance.

Someone please enlighten me as what this means
-
It’s referring to special relativity, which has a speed limit (speed of light) and reference frame invariance (physics works the same …

whether you’re staying still or moving at a constant velocity). These two principles seem to contradict each other. For example, if two …

people both move at 99% the speed of light, but in opposite directions. Intuitively, one would think that one person sees another person …

moving at 198% the speed of light. This contradiction is avoided by requiring a formula to “add” velocities that isn’t just addition.

Oops. Guess I should have been more specific; what is "parallelize" in this context?
-
It’s playing with the idea that the universe is a simulation running on a computer. If there’s a speed limit, it should be possible to …

partition the universe into smaller parts, and have the state of a certain part depend only on the previous step of the adjacent parts.
