==========
In our universe, when you change from a non-moving perspective to a moving one, or vice versa, that change of perspective is represented by a what's called Lorentz transformation, which is a kind of squeeze-stretch rotation of spacetime that I've mechanically implemented with this spacetime globe. A quick reminder - spacetime diagrams plot position on the horizontal axis and time on the vertical axis, and something moving as time passes traces out a path through spacetime called a worldline. One of the first things you might notice about Lorentz transformations is that events that were at different places at the same time before the transformation aren't at the same time after the transformation. This means that from the perspectives of people g...
