Simultaneity and Translational Symmetry

Authors: Eric Su

Two identical stopwatches moving at the same speed will elapse the same time after moving the same distance. If both stopwatches were started at the same time, there will be no time difference between these two stopwatches after both stopwatches have elapsed the same time. Both stopwatches will continue to show no time difference under identical acceleration. Therefore, both stopwatches show identical time in an accelerating reference frame if both stopwatches were restarted at the same time in a stationary reference frame. Consequently, a physical system that exhibits Translational Symmetry in its motion demonstrates that two simultaneous events in one reference frame should be simultaneous in another reference frame.
