Mathematicians can't prove that a physical theory is correct, all they can
do is show that changing the coordinate system (for example by rotating the
X and Y axis) does not result in different physical predictions.

By the way, just 2 weeks ago the best test ever made of Einstein's
Equivalence Principle was performed in a gravitational field one million
times greater than Earth's and Einstein passed the test with flying
colors.
Test of the Einstein Equivalence Principle near the Galactic Center

Mathematicians prove things Physicists don't. Physicists show that some
ideas are less wrong than others and they do that by
