- This assertion is only true in the literal interpretation of SR. But
- this thread is discussing possible synchronization that supercedes these
- hypothetical SR limitations. If super-synchronization using infinite-
- velocity beams were possible, then the fact that clocks in different frames
- moved at different rates would cause no problems for super-synchronized
- clocks or observers. It would lead to a somewhat different understanding of
- the meaning of SR, but nothing in conflict with observations or experiments.
-
- Think of time dilation as affecting all physical clocks within a frame
- instead of affecting time itself. Then a lot of things start to make more
- sense. -|Tom|-
