Nevertheless, Ken, if there is a difference in the absolute motion from top to bottom, then this means that there is a relative motion. If you have one bird flying horizontally at 15 mph out a 1st story window, and another bird flying horizontally at 30 mph out a 30th story window, there is relative motion between the birds.

One small note : there are no clocks in the Pound Rebka, it is about atoms catching photons, in accord with Einstein's thought experiment where a photon should turn redder when escaping from a gravitational source. The photon is emitted, and cannot be absorbed because its frequency has been changed by gravitational redshift. Then the upper part of the experiment is lowered at a fixed speed, in order to compensate for the redshift, and then the photons are absorbed again, by the same sort of atoms that emitted them below. > No aether, no motion, no absolute anything is require.

I could say something about an universe sized elephant in the room, but I am keeping that for a later "time". First finish my text about the Arrow of Time, and submit it to Nature.

Aha, you even try to alter the meaning of the term "absolute motion". No Ken, if a building does not move wrt light, it will always be dark inside! "Absolute motion" means the motion of things relative to a physical (but not necessarily detectable) reference; I'm sure that people already gave the example of sound relative to the air. In discussions of "relativity" it particularly refers to such concepts as Newton's "absolute space" or Lorentz's "stationary ether". Have you been stuck on this starting point for 5 years now, or was it longer?

No idiot I didn't try to alter the meaning of absolute motion. Absolute motion is that motion of an object in a staionary aether and light is being transmitted by this stationary aether at a constant speed and therefore absolute motion of an object is also that motion of the object wrt light.

No absolute motion is that motion of an object wrt light. At the bottom of the buidling the source is at a standard frequency....light from the bottom to the top shows a frequency shift that means that the top is in a different state of absolute motion.
