Could somebody please clear up this paradox for me. Two objects, A and B, are moving past each other at close to the speed of light relative to each other. So far so good. Object A looks at object B and sees object B fly by at close to the speed of light. Object A figures time dilatation takes effect and concludes the clocks on B are moving more slowly than on A. Object B looks at object A and concludes the same thing. A while later, the two objects meet up with each other and compare clocks. Are their clocks indicating the same time or different times? Which clock is ahead? If none of the clocks are ahead, then what happened to relativity? This ongoing paradox seems to undermine the entire theory. Could somebody clear up this paradox. Thank you.
