What part of "all frames are equally valid" don't you understand? Or do you not get that if we use an inertial frame where the twins are both moving with the same constant velocity, they do NOT have identical ages at any given moment in this frame? (assuming they had identical ages at any given moment in their rest frame) Jesse -- You received this message because you are subscribed to the Google Groups "Everything List" group.
