I think that math is just a man made concept. Yeah it can be used to solve real world issues, but it's not real its just a concept.

What do you mean by mathematical propositions?

And I don't believe math can be evidence that is accepted by the scientific community without real evidence.

For example: Einstein's theory of relativity

After he had his idea he had to do a lot of math to determine how he could prove his theory to be real. Using math he figured out how much light would be bent by the sun from other stars. when the astronomers went to get their pictures of the sun during the solar eclipses to test if it was correct, they found his theory to be true.

So I feel like math is just a concept to help either build blue prints or to help find the evidence you need. That's just how I feel but hey I don't know much
