There could be one universal reference frame which is inertial (non-accelerating) and where clocks behave normally so that time can be defined in that frame. But then any other frame moving at constant velocity (with respect to it) will also be an inertial frame and have normal clocks. The aging difference should be noticeable by any of those inertial frames.Rogerhttps://www.blogger.com/profile/03474078324293158376noreply@blogger.comtag:blogger.com,1999:blog-8148573551417578681.post-42090434472887825462012-01-07T09:50:28.725-08:002012-01-07T09:50:28.725-08:00To me, the twin paradox has always seemed to imply...To me, the twin paradox has always seemed to imply a universal reference frame. Otherwise, how could the space-travelling twin age more slowly?A K Haarthttps://www.blogger.com/profile/05897490979828603179noreply@blogger.com
