One way to look at is that the, "cosmological constant",
that indicates the overall curvature, is,
mathematically: non-zero, yet, vanishing.

Then, it's no different from flat overall, while,
it's not saying much about curvature as the mere
geodesy as according to whatever is gravity.

So, that's not the usual interpretation, of GR, say,
that the cosmological constant is an infinitesimal,
yet it helps make it so that space-time isn't discontinuous,
and other usual reasons why "space-time is flat".

"Relativity, of motion, the theory" doesn't much say
anything and just asks mathematics that fit. So your
issue is as much with poor mathematicians as blind physicists.

The theory of it where each greater frame is that
everything within the frame is absolute to it,
may be also like an aether theory and as with
regards to the Mach-ian, why it's so that there's
a sort of local relativity theory and an absolute
theory, together.


It's agreeable that non-Euclidean geometry is
rather non-sensical or rather non-physical,
though there's torsion to figure out, and
the independence of rotating frames. I.e., of
course Euclidean geometry is sensical and physical,
or, that is to say, "space-time is flat".
