Note: the forum did not allow completing this long question. The remaining part read: "Velocity Between Clocks Where Either Clock May be Considerd at Rest". This board has been swamped by challenges to Relativity, SRT specifically. This issue arose in another thread and I feel it deserves specific attention and response from Relativists. The response can and should be enlightening. My question is to see how Relativists answer this situation. CASE: A clock is placed into a geosynchronous orbit with earth. As we know GPS clocks are compensated for velocity but do so using the earth's pole as a reference point. This scenario is simular but more distinct as will become obvious when considering the ramifications of the question. 1 - Question is, (with GR affects ignored) what is the relative tick rate of the orbiting clock with respect to earth surface bound clocks. Keep in mind that the orbiting clock has velocity just as GPS clocks have velocity. 2 - What is your explanation for the fact that if you apply the concept of Relativity's SRT where the orbiting clock is now considered to be stationary that there is no relative velocity between the orbiting clock and the surface clocks.? SUMMARY OF PROBLEM: 1 - On the one hand you have a known case of velocity of the clock and it would seem that time dilation must be considered. 2 - The fact being that there is no relative velocity between clocks for SRT to function. 3 - Does not this raise the issue that Gamma may be valid as to motion but that SRT is invalid in it's overall concept of such affects being relative velocity between clocks and not absolute velocity of motion and not between clocks?
