How does it compare with The Mechanical Universe series. http://www.learner.org/resources/series42.html 42. The Lorentz Transformation If the speed of light is to be the same for all observers, then the length of a meter stick, or the rate of a ticking clock, depends on who measures it.

I think there is definitely something going on with the rate at which clocks 'tick' and their interaction with the aether, but it is a physical interaction. Clocks 'tick' at different rates due to their respective interaction with the aether. The rate at which a clock 'ticks' has nothing to do with time.

There is definitely something going on between the rate at which clocks 'tick' and the clock's interaction with the aether, and there may be some length contraction as stuff moves through varying degrees of aether pressure, but my gut tells me length contraction and time dilation are cop-outs. An atomic clock on top of a mountain will 'tick' slower because the aether pressure is less and the oscillation will not be as compressed.

In Aether Displacement, the speed of light is defined at 'c' with respect to the aether. If we have a train where the aether is at rest with respect to the train and two photons are fired from the back of the train and one light year from where the photon was fired is an Observer on the train and the instant the Observer on the train receives the photon the photon is received by an Observer on the embankment, both Observers, since they know the state of the aether, both determine the photons to have been emitted from the same place in three dimensional space and to have been emitted one year ago. If you want to be all hung up about where the photons were emitted from in three dimensional space relative to the Observer on the embankment and how that means the light traveled at greater than 'c', that is your issue. Whenever you want to have a cow about the speed of light, add water at rest in reference frames to your gedanken.

Observations show that clock "tick" faster on the top of a mountain compared to clocks at the bottom of the mountain. This was predicted by general relativity and confirmed experimentally. |
