His specific question was prompted by the statement that time dilation is reciprocal.What other impression might he get from anything I've said?
Your posts state that it all is a result of one person having a speed while the other one is at rest. You seem to be stating the opposite of what phinds was saying. Can't you incorporate the reciprocal nature of time dilation into your discussion and explain why the "person at rest on earth" could be the one with the slowed down "biological oscillators" just as validly as the person moving at 0.5c in a spaceship?Then why does one person age more than the other?WHOA HERE ... unless I have this totally wrong, time does NOT slow down for you when you get near the speed of light. It APPEARS to other inertial frames of reference to have slowed down but to YOU it doesn't seem to slow down at all. To you it seems like things in the OTHER frames of reference have slowed down (and of course, they would disagree).
