Am also layman, but my understanding is that “dark matter” is just kind of a placeholder for some unaccounted for mass that’s detectable by inference. i.e. we can’t see anything that would produce that gravity, but we can detect that something out there has mass.
with black holes still an option for the behaviors we are seeing accounted to ‘dark matter’ why are we bothering with another, seemingly ephemeral type of ‘matter’?
That’s actually a theory that’s gaining traction again. Primordial black holes left over from the Big Bang are one contender for “dark matter”:

Keller Williams style! Love it.
Saw Keller live when I was in college; probably the best show I’ve ever been to. Also didn’t hurt that the crowd was a bunch of hippies, and we collectively hotboxed the Warner Theater. 😆
It probably smelled like the art teacher’s office in there for at least a week after.
