Do physics start with a set of basic assumptions, and from there, derive a theoretical system that fits well with experiments? Can the best physical theory explain everything?( Including its own underlying assumption as a deductive system) Can physics answer the question: why is there something, instead of nothing?( even the existence of the laws themselves) Can physics explain the emergence or happening of the big bang? if so, then what underlying assumptions is needed? if physics is more or less about finding regularities in nature, and calling it laws of nature. Do the laws emerge 'before'( i know the absurdity of using before) the universe? if so, then if there are no laws, how did the universe emerge? Did the universe 'precede' the laws? if so, if there are no universe, how did the law emerge?
