How could we possibly tell if it was really the same space?
What is the reference point? ;-)

One POSSiBLE way is the PEG-in-the-HOLE Test ..you use the SAME hole.
Temperatures EQUAL, a UNiT plug CANNOT fit a UNiT hole in REAL space.
But, don't FORGET to use a DiFFERENT plug. Hope this helps. ```Brian.

... Einstein did not use any argument related to
simultaneity or Doppler shift in his analysis. I discuss
Einstein's resolution and several conceptual issues
that arise. It is concluded that Einstein's resolution using
gravitational time dilation suffers from logical and
physical flaws, and gives incorrect answers in a general
setting. The counter examples imply the need to reconsider
many issues related to the comparison of transported
clocks. The failure of the accepted views and
resolutions is traced to the fact that the special relativity
principle formulated originally for physics in empty
space is not valid in the matter-filled universe.

Indeed... It is called 'matter'. )

GR book recommendations, is spacetime concept just mathematical?
