  There was some ancient religion where their god or satan figure was responsible for time - literally the god/satan beings way of destroying the universe. Wish we could figure out some better ways to experiment with time. Seems like it's very telling of what's really going on that it's so different.

  But how would we know if all spatial dimensions were moving along a constant vector? We can't rely on redshit/blueshift if the medium of transmission itself is moving like everything else. The next question might be "moving in what, then?" but then why not abstractly ask the same about time.

  This is a bit of a tangent, but the idea of "moving through time" always struck me as a little weird, because the concept of motion is dependent on time already. I like to think of things having a shape that exists along the time axis in addition to the spacial ones. The 4D shape of a thing is fixed, but captures within itself what we perceive as motion in 3D space.
