Mr. Hertz: The article, "Poincaré and Cosmic Space: Curved or not?" by
Helge Kragh gives the history of how the elementary error of reifying
space became respected and prestigious thanks to Schwarzschild and
Einstein carrying it over the finish line. Most scientists knew it was
fallacious and it only gained acceptance slowly. From the article it
appears that the key is the idea that non-Euclidean geometry is more
empirical than Euclidean. After all, no one has been able to prove the
fifth postulate that parallel lines never meet. However, no one has ever
proven that they do. The idea that the universe is spherical given the
vast extent of it now known would make the curvature infinitesimal so it
is non-falsifiable. This shows that non-Euclidean geometry is not more
empirical.

Elementary logical analysis remains sufficient to disprove non-Euclidean
geometry. Obviously spherical geometry and geometry describing other
shapes is valid. It is only the reifying space that is absurd.

Poincare correctly understood that geometry cannot be reified (in

of reality, but only geometry together with physics.'"["Poincaré and

You understand 'geometry' as 'relations in euclidean space', while
actually higher dimensions have also an embedded geometry.

Therefore you are right, that Euclidean geometry does not tell anything

But what about spaces with higher dimensions, from where our observable

Since our universe contains matter, the superset of our observable space

Such a space could be build from the equivalent to a point (but with

This had to look from any perspective like a valid universe, because our

E.g. assume, that each 'point' is actually a bi-quaternion, which are

p' = q * p * q^-1

Often "convolutional setting", symmetrical/anti-symmetrical
left-right right-left.
In something like Geller's Heisenberg group pseudo-differential,
gets involved two symmetrical centers their dynamics.
(Kohn, Stein, Cummins, after Poincare, variously real, "complex",
"real analytic", ..., operators, kernels/cores, pseudo-differential.)
