[QUOTE="Stephanus, post: 5574159, member: 552565"] Okay... [I]A travels to a star far away at near light speed, A would see B's time dilate. B would also see A's time dilate[/I] Yes-s-s, but you must account for doppler effect. Actually what A (and B) actually see for each other opposite will be much slower. It's because of Doppler effect.[I]Twin paradox revived: What would happen if A returns to B at a very slow speed? Then both frames of reference would see each others' time dilated.[/I] Yes. But don't forget doppler effect. Actually both will see (no matter the velocity is) the other clock runs faster. But after adjusting to doppler effect the other clock actually runs slower wrt the observer.[I]A thinks 20 years passed, but only 10 years passed for B, ans B thinks 20 years passed, but only 10 years passed for A.[/I] Come on... ##\gamma = \frac{1}{\sqrt(1-v^2)}## ##2 = \frac{1}{1-v^2}## ##v = 0.866## In my hometown 0.866c is not in the very slow category. :smile: But the essense is.., slow or not. Both will see the other clock dilated. Yeah, that's why flight seems shorter with a beautiful stewardess, [/QUOTE]
