>>12054460Calling it a singularity would be wrong, though.
A black hole is an all encompassing term that conveys they entire idea of what the "object" is, even including the plasma/gas disc around it. Just calling it a singularity would not only miss all of that, but mathematically just be wrong.
Same deal goes for Dark Matter/Energy. This currently encompasses whatever it is and its effects. I'm sure in at most a couple hundred years, we will have figured it out and we'll have many, many terms for whatever the fuck is going on there each with its own equation. But for right now, calling it Dark Matter works because everyone knows what you're talking about.
