Dingle paradox Hi I think Dingle he was right in questioning Ensteins special relativity of uniform motion and time My question is the same as Dingles Einstein said that the time of the moving observer will slow from the point of view of the resting observer If I consider the moving observer at rest then the previously resting observer will be in motion so his time will slow Ignoring acceleration of course Can both observers be right Dingles answer is that they can not becouse this would invalidate the theory of time dilation I tried to find a simple answer on the internet in defence of Einstein but without any success Its strange becouse this is such an obvious question that it should have been answered clearly by now Thanks sr
