There's a certain nominative-deterministic inevitability to all this. There are these things called black holes that apparently are a full of a lot of stuff and aren't completely understood. And there's this mysterious stuff called dark matter that has to exist but seems to be hiding. My mom would be yelling "'Come on guys, join the dots". And who would blame her.
- chc 8y agoYou seem to be thinking that nobody considered black holes as dark matter candidates, but that's not the case. The two big theories around the origin of dark matter are called WIMPs (weakly interacting massive particles) and MACHOs (massive compact halo objects), and MACHOs include black holes. The reason MACHOs aren't widely accepted is because the evidence (e.g. lensing measurements) doesn't suggest there are nearly enough massive invisible objects to account for a significant portion of the dark matter.
