As a layman who’s into physics it took me like a decade to understand what is “wrong” with them. No educational string theory video is prefaced with “Hey this is an old unprovable theory that is essentially dead in the water, but it has some cool math tricks and is fun to think about” as they should be.
I wouldn’t say “just”, experimental proof seems huge.
But if you want theories just go to PBS space time and open anything that isnt string theory or mond.
i say do watch the ones about string theory and mond so you can see why/how they’re wrong
