>All the other evidence for black holes is that special relativity predicts them
Wrong. Lots of indirect evidence: the stars orbiting the Galactic Center, x-ray binaries, active galactic nuclei...

General relativity, not special

>and breaks down and becomes nonsense when dealing with them
You are mixing up the event horizon and the singularity. The singularity where spacetime curvature becomes infinite probably ought to be modified in some deeper theory of gravity beyond general relativity. But the event horizon beyond which nothing can escape is what really defines a black hole, and that is in a regime in which general relativity should be valid.

Wouldn't it be better to say the core is a very dense lump of mass instead of a singularity?

Einstein said it was a singularity and we have to do what he says

No, GR is the theory which describes black holes and it says singularities form. There is no known physics which could halt the collapse.

I believe the Chandrasekhar limit uses special relativity

There is some principle in QM, I forgot the name, that says particles can't occupy the same space. So 1 particle per whatever radius this "space" is would be the limit of compression.

It's not an actual photo in any reasonable sense of the word. It's a computer generated image of a model created by a group that might or might not have connection to reality.

It's Pauli's Exclusion Principle. It's what supports white dwarfs and neutron stars through degeneracy pressure. It has limits, it can only supply so much pressure before it fails.
Under GR there is no finite force that can halt collapse once it gets close to the Schwarzschild radius.

what is it about black holes that makes them the number one most popular popsci topic of discussion amongst the brainlet soience fangoys?
is it the comic bookish aspects of the spectacular, unrealistic and completely non disprovable conjectures which go along with the topic that make black holes so popular amongst the scientist posers and wannabes?

I think you can say that about neutron stars. VERY dense lump of mass. they are pretty bizarre as they are. once that collapses it becomes reaaaally small. at least judging by the event horizon. what's past it is anybody's guess.
