Please do not conflate the broad "theoretical physics" with the very specific "beyond the standard model" physics questions. There are many other areas of physics with countless unsolved problems/mysteries.

Sure, there are things like "Really, how do superconductors work?", but nobody (mostly) believes that understanding things like that requires "new physics".

And, I think, most people would place that kind of stuff under "solid state physics" anyway.

oh i dont know, being able to predict the path of a particle seems pretty basic to me, and it cannot be done for any given particle.
