comment What would be the consequences of time not being “relative”
Here's a slightly different way to think about it: Relativity is a consequence of there being a maximum speed at which information can travel from one location to another. In our universe, that maximum speed is the speed of light in a vacuum, c. If you make c infinite it's easy to see how time becomes fixed, since every location in such a universe can instantly "see" clocks at every other location. There's no relativity of time in such a universe! However, the moment you make c finite, it turns out you cannot create a self-consistent universe without some form of time-space ambiguity.
