Even in special relativity, a time dialation occurs only between two reference frames whose velocity w.r.t. each other approaches the speed of light. Since the cord is very strong, a simple rotational transform will reduce the problem to one where their velocity is 0, thus no time dilation occurs. Of course, since the reference frames are undergoing acceleration, all bets are off. tektronix!iddic!bobr Robert Reed
