To move this away from “politics” or whatever I’ll disagree and say that it’s not insane, it just stupid.
Dark matter was named by Fritz Zwicky, a Swiss astronomer who postulated that “dunkle materie” could explain the motion of galaxies in the Coma cluster. He simply referred to it as dark the amount of matter in the Coma cluster exceeded the amount he could account for by studying light.
The idea of dark matter was largely ignored until Vera Rubin found that the rotation curves of galaxies required a halo of - guess what - some unseen diffuse matter around galaxies. In other words, dark matter. The nature of dark matter is unknown, but I believe the most popular theory is WIMPs, relatively massive particles that only interact via the weak nuclear force and gravity.
First Zwicky would have been a valued tuscl poster. He liked to call people “spherical bastards” because they were bastards no matter which way you looked at them. He was also a genius who came up with the idea of supernovas in addition to dark matter. And did other work that escapes my memory.
“Black hole” originated - I think - from work by John Wheeler. However, I think he got it from somebody else and that it was a comparison between collapsed stars and the black hole of Calcutta. I’m sure it’s traceable if you really care to look it up.
I suspect the astronomer being interviewed mostly wanted to make a for herself and came up with something she thought would be interesting. CNN was irresponsible for letting her do that. But I’m sure she knew the history. An astronomy elective at a university probably covers that. Maybe not all of the personality stuff about Fritz Zwicky but I thought he seemed cool.
