My point is that math was written assuming all mass bends spacetime. This cannot be proven, therefore the math cannot be proven correct in all cases.

It is important that we all understand what makes Maths different from Natural Sciences.

- Maths are not about the world we see, they are about the concepts we can express unambiguously.

- Maths are not subject to observation, experimentation or the scientific method. You do not accumulate evidence trying to get consensus around your hypothesis. You show unambiguous proof or you have essentially nothing.

- Most important, in Maths each field of study has its own axioms that are either proven to be internally consistent (no theorem can be proven both righat and wrong) or internally inconsistent (you can prove both a statement and its opposite) which is the death knell for that field, or is waiting for final proof of consistency. In some cases the impossibility of a proof of consistency has been reached.

In other words, if you define your field of study to be a flat disk, a sphere, a timeless point in a pin, an infinite void, or anything else, you still only have a set of axioms and some theorems that you derived from the axioms. Maths cannot prove or dis-prove anything in the real world.
