Since SR physics has considered motion strictly as the separation of bodies,
no longer can a body move through space except with reference to another body.
Consider an infinite number of frames (A, B, C, ... A1, B1, C1,...An) with common x axis.
All move near the speed of light relative to their adjacent frames.
If we choose as a frame of reference, say frame A, we have an infinite number of frames
confirming the motion of A. If we now remove all frames except A, A is at rest.
Not because of any dynamic change applied to A, but because the motion of A was always
and only with respect to another frame.
It is useless to argue whether A or any other frame is actually in motion with respect to space.
Although this seems awkward, it is understandable in the framework of special relativity.
If we now consider a mass as the origin of A, and A is the only mass in the universe,
is it still useless to consider the motion of A with respect to space-time?
Would it not be possible to measure the gravitational time dilation on the x-axis of A to differ with significant motion along x?
