They follow different paths, which each clock travels at exactly       1 sec/sec. Since the paths are different, it follows that the amount of time       between the start and the end of the experiment will indeed differ.              Again, this is quite similar to why two identical odometers, in two identical       cars, show different distances between Chicago and New York, because they       followed different paths between these two cities. The difference is due to the       geometry of the problem.              You recognize that you are not interested in going into the equations that       show this geometry, because you are not familiar with any math regarding this       problem. Proceeding in that way, it will get too difficult to you to understand       any of the basics of Special or General Relativity.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
