Note that it’s always good to keep in mind that “dark matter” is a scientific hypothesis at best, and really just a placeholder for trying to quantify some form of mass / effect that can’t be directly observed.

I love the black hole angle, though, especially as a bit of a Kurzgesagt fan.
Indeed, this one is probably the most fascinating hypotheses I’ve ever heard when it comes to cosmology:
