In spite of developing the theory (General Relativity) that was used to prove that black holes could exist, Einstein didn't think that they were possible.
I think it's safe to say that physicists "universally" agree that black holes do exist.
(I am not a physicist.)

We had this famous Schwarzschild radius (3 kilometers per sun mass) in Astrophysics lectures when I studied. There was a lecture on star building and evolution, one on supernovae, and a seminar where I once held a talk on x-ray binaries, which consist of a large star (e.g. a Red Giant) and a very compact object (e.g. a White Dwarf, Neutron Star, or Black Hole). Mass flows from the large to the small component, building a so-called "accretion disc", and hits the surface of the small component so hard that x-ray radiation is generated, which can sometimes be measured on Earth, like the rotating beam from a lighthouse. Fascinating subject.

I agree. Never took a physics course beyond college basics, but I've been fascinated with the concepts in astro- & particle physics for decades.
The Great Courses (online) has some excellent lecture series on advanced physics (as well as other topics) and, of course, there are plenty of excellent books for the layman.

The report on the black hole is at the end of the video titled "Breakthrough of the year and Runners-up".
