Einstein said that all frames are equally important. Now, assume that I (or body A) was moving at a velocity of V. If body B was considered to be stationary and I was travelling away from it at a high speed then my time would slow down. This I understand. But... If body A was the inertial frame and taken to be stationary then body B is travelling away from body B. This is true if one subscribes to Einsteins theory. If this is true then body B's time is slowing down at an equal amount to body B (assuming that both B and A have an equal mass). So in theory (according to what I am asking and along with Einsteins) they are both slowing down in time at the same rate. So, even though body A is moving away, according to Einstein body B is equally moving away, so they are going at the same speed through time as there velocity is the same depending on the frame. So nothing slows down in time if all frames are equally important. Am I right?
