I wonder the same thing too! Seems like if one could explain some of these better though: https://en.wikipedia.org/wiki/List_of_unsolved_problems_in_p... with the model, then that'd be it (just like https://en.wikipedia.org/wiki/Tests_of_general_relativity) - that's all physics is at the end of the day. Better models.

And arguably there's value though in looking at the patterns in the history of science and being guided by them.
