It is true for EVERY clock IN INERTIAL MOTION, and hence cannot be preferred.

Wrong. Hafale used the SR formula for time dilation in the Hafele- Keating experiment, and the planes in the experiment were in the Earth's atmosphere, unlike the satellites.

Let's get some things straight. 1. SR makes certain statements that are true under certain circumstances and other statements that are true in other circumstances. 2. It is a mistake to think that if SR makes certain statements about two *inertial* reference frames, that the same statement will apply when there one of the frames is not inertial. 3. Likewise, it is also a mistake to think that if SR makes certain statements that apply to two *inertial* reference frames, then it ONLY makes statements about cases where there are only inertial reference frames. It just won't be the same statements. 4. Any attempt to misapply a statement that SR makes but outside the circumstances intended, is purely pilot error and evidence of user incompetence. 5. Just because you see an equation in it with (1-v^2/c^2), doesn't mean that it an SR treatment. Recall that SR is a *special case* of GR, and that SR is therefore embedded in GR, so that when you are using a GR treatment, you will see some things that are reminiscent of SR, even though you are outside the special case where SR applies. 6. The presence of the atmosphere has absolutely nothing to do with time dilation. Time dilation is also observed routinely in labs on the Earth's surface, as well as IN the material of the earth!

I think the issue is what corrections or adjustments a necessary for a real case than involves a gravitational field so that it treated as if it is conformant with the requirements of SR. For example, the original twin paradox involved the earth, but there were no adjustments made for the Earth's gravitational field. > 3.

My point was that Hafele's treatment of time dilation for a plane can also be applied to a GPS satellite, as a plane is closer to the Earth than a satellite. |
