Each person observes the other person's clock as running slowly....hence the paradox. [EDIT: As Xaccers said, to the person in the rocket, it is the person on Earth who is moving fast...and moving clocks appear to run slowly]

It goes into more detail in the 2nd link I gave. It also explains how the paradox is solved.


Another interesting thing the 2nd link mentioned...according to general relativity, clocks at high gravitational potential run more quickly. (time dilation comes from special relativity).

Reminded me of something I read ages ago (can't remember where though)....a clock held at the top floor of a huge skyscraper will run faster than a clock held a ground level, due to the gravity.
