Liz, Not at all. What SR shows that there are relativistic situations in which it is impossible to establish simultaneous clock time t values, for relativistic observers to agree on the clock time t value of some event, and then ONLY in the case that relativistic frames are different. When the frames are relativistically mappable (no relative motion or acceleration) then t value simultaneity can always be established.
But none of that applies to the notion of the same present moment in which all these relativistic effects occur. Clock time simultaneity is NOT the same as sharing the same present moment, as the different t values of the reuniting time travelers proves beyond a doubt.
