The tone of your messages come off as a bit confrontational, that's probably the reason sorry!

Anyway, like many other situations before, there is probably no single fix to dark matter.

There's probably a huge swath of cold hydrogen that still goes undetected that would explain part of the small scale stuff (bullet cluster and such), and then some quantum gravity or modified gravity to explain the very low range stuff.

Also, there are papers out there about how large scale simulations assume smooth distribution of matter, but then when computing with the actual distribution of matter, the some dark matter phenomenons tend to disappear.

Anyhow, exiting stuff to get new physics to learn about!
