That's not meaningful to me, because I don't know how to       determine how much she aged while the message was in transit.              But if I'm mutually stationary wrt the array of clocks that I have       previously described, which provides a "NOW" for me extending throughout       space, that DOES give me a meaningful answer to the question of how old       she currently is. And by "meaningful", I mean that I REALLY believe       that she is currently that age. The only way I can be wrong about her       current age is if my equation for the rate ratio of the two clocks is       wrong. I'm confident that it is correct. I think it IS experimentally       testable.              I don't understand what you meant in the above, when you said       "regardless of whether anything else in the universe       is affected". Although I realize that the way I accelerate affects what       I conclude about how her age changes, I don't contend that that has ANY       effect on what other observers (including she herself) conclude about       her age changes. Different people disagree about simultaneity at a       distance. That's just the way special relativity is.               Michael Leon Fontenot              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
