AFAIK, the mass of a black hole is concentrated on a point called the singularity, this is the reason for its extreme gravitational pull. So for black holes to behave the way it does, it needs a singularity. Are you suggesting that this singularity is made of dark matter ?
How does this dark matter singularity become that foggy patches shown in the NASA Hubble map ? To me, this doesn't seem to solve dark matter but just complicates things even more, lol 😂

AFAIK, general theory of relatively is proven. I don't know if singularity makes space-time curvature infinitive, that's kinda confusing because infinity a theoretical. For example, we consider sun's rays as parallel even though its not at an infinite distance from earth, so the context matters.

We've invented a lot of such things, take charges for example. Someone went up and said "Let's assume there are 2 kinds of charges, +ve and -ve. Unlike charges attract & like charges repel", and we just kinda roll with it. Why does unlike charges attract & like ones repel ? Why does it have to be like that ? These questions don't matter as long as we're able to make useful predictions with our model. -ve numbers are also an invention, before there were only +ve numbers, and none before that

Yeah, time is just a way for us to measure change. I remember Jacque talking about this in the TROM documentary, sun didn't rise because its 6:00am, its actually the other way around. We get stuck in this mentality of seeing measurement as the thing you're measuring.
I think your way of looking at it might me more accurate. Its not time slowing down, its just rate of change of atoms or something that changes, that's usually what we mean when we say time slows down.
