As "bouwe" says in his reply, the twin paradox is not as Mark explains. It can be better understood if we imagine two space ships, A and B. A is "not moving" and B passes by at a high constant speed. According to the relativity theory, from A's point of view, B's clock is running slower. But from B's point of view, he is quiet and A is moving, so A's clock is running slower. There is no way to decide who is moving and who is not, because "movement" is a relative concept that depends on the observer. So if B turns back and reaches A (or viceversa) and they compare their clocks, which of them will late? I don't know the answer yet, so for me it IS a paradox.
