Thanks for the link! I guess this is what I don't understand, "As long as there are no accelerations, the effect is symmetrical. With acceleration you still have the effects, but the one who accelerates will end up with a clock that has run slow." ~ Swansont.. Here he says that "the one who accelerates will end up with a clock that has run slow", but if movement is completely dependent on the frame of reference than how can you say that the guy who is accelerating will have a slower clock?.. because from different reference points you could say that they are both accelerating. It is hard to explain what I am talking about.. I'm sorry if I'm not being clear.

Hi guys, I'm just a high schooler who was thinking about general relativity and couldn't quite get a grasp on one certain idea.. I asked my physics teacher this, but he wasn't really quite sure himself. If you have empty space, and you have to objects, and one of them is "moving" at nearly the speed of light, and the other is "sitting still".. then according to Einstein (correct me if I'm wrong) the one with the higher speed would have a slower time frame (its "clock" would slow down) relative to the other object.. but if there is no absolute frame of reference then how can you distinguish which object is "moving", because really they are both moving relative to each other. If this is the case, how could you actually distinguish which one was on the "slower" time frame...? Thanks again!! Just let me know if I didn't explain my question well enough..
