Huh? Physics does not depend on "proofs", it depends on evidence. Mathematics depends on proofs but mathematics is an intellectual recreation that is occasionally useful, it is not in itself a science.

No, physicists when they find that the law doesn't hold, want to know why and under what circumstances and when the figure that out then they modify "the law" accordingly.
Can you give us some examples of "the law not holding" that are regarded as "well understood and physically unimportant" that don't involve your own misunderstanding of simplified models used for computational convenience?
