I don't know a lot of advanced physics or quantum mechanics, but black holes also confuse me.
I would imagine that black holes show the limit of modern physics, there are still things to learn, and models of physics will probably be adjusted in the future.
I guess there are physicists who are able to predict how a black hole works and appears, and how it can be explained, but I haven't read about it.
I mean, yeah there's tons of theoretical work. Predictions about lensing and structure have been done and verified. We've taken pictures of black holes. Susskind did a big fancy simulation for Interstellar that lined up great with them.
