Most theories in physics will never be fully proven or disproven if a theory is formed properly, it should be possible to disprove it. it would be disproved through some empirical observation. even if a theory has not been disproven, that doesn't mean it is proven. all we can say is, "empirical observations to date are consistent with the theory". but potentially, at least, there could be future empirical observations which are not consistent with the theory. this means that such theories are "fallible". otoh, one can also formulate totally unfalsifiable theories, such as the existence of god or faeries or untold dimensions wrapped up in tiny strings that manifest in a multiverse. these theories are called fantasies, because they can never be disproven or tested. instead, one relies on "faith", which is to say one relies on "authorities", i.e., vested interests who want to perpetuate this or that fantasy for their personal reasons.
