Disclaimer: My domain knowledge on these topics is pretty minimal. I'm a "physics fan".
From what I understand about relativity, if there are two identical objects, A and B, and A is stationary and B is not, then A will observe that B's time is elapsing more slowly than its own. It will also notice that B is shorter in the direction of travel than A is.
Now let's assume that A and B could somehow see through time as well as space (this is potentially where the question breaks down). I suppose they would see something like a series of cubes, representing each instance in time, with all the objects in different positions.
If both A and B were now stationary in space, but B was traveling twice as fast through time than A was: Would there be any relativistic effects A would see as it is observing B?
