EDIT: Let’s cool it with the downvotes, dudes. We’re not out to cut funding to your black hole detection chamber or revoke the degrees of chiropractors just because a couple of us don’t believe in it, okay? Chill out, participate with the prompt and continue with having a nice day. I’m sure almost everybody has something to add.
Yeh, that’s how the scientific method works.
Observations don’t support a model, or a model doesn’t support observations.
Think of a reason why.
Test that hypothesis.
Repeat until you think it’s correct. Hopefully other people agree with you.
People are also working on modifying General Relativity and Newtonian Dynamics to try and fix the model, while other people are working on observing dark matter directly (instead of it’s effects) to further prove the existing models.

We are in the “testing hypothesis” stage. And have been for 50ish years
“Repeat until you think it’s correct. Hopefully other people agree with you.”
Dark Energy has entered the chat.
For those with time to spare: study all you can about neutron stars (including magnetars and quark stars), then go back to “black holes” (especially their event horizons and beyond) and there’s a good chance you’ll feel like a lot of aspects in BH theories are mythologies written in math - all of it entertaining, nonetheless.
For those who seek extra credit, study zero-point energy before reflecting on cosmic voids, galaxy filaments, galaxies, gravitationally bound celestial systems, quantum chromodynamics and neutrinos. Then, ponder the relativity between neutron stars, zero-point energy and hadron quark sea.
The attempts to measure dark matter directly have gotten incredibly sensitive and still haven’t found anything.
Multiple experiments to detect dark matter directly here on earth have been constructed. They expected a handful of detections a year given the estimates of local dark matter densities. Those experiments have not yielded any detections. This sets very restrictive limits on candidates for particle like dark matter.
I’m fully aware of astronomical observations that suggest the need for dark matter. That’s not what I was referring to.
So far, astronomical observations are all we have, the lack of terrestrial observations have only been able to elliminate candidate particles, not measure them.
Yeah, it’s legitimate science being done, but some people treat it as sacred and would fight you to no end because they say Dark Matter is some certainty, rather than approaching it with the proper scientific skepticism or with a statistical outlook.
For the most part believers in Dark Matter are cool, but a vocal minority practically worship it as the only possible truth.
The certainty is that there is something there, we just don’t know what it is. The name “dark” anything is irrelevant.
If a new hypothetical model showed that either some far off unobserved mass(es) or the currently observable mass can have the gravitational effects that were previously explained by dark matter, or any other far off idea about the nature of gravity at large scale: then there would be evidence there is nothing there. Currently there is no evidence that something is there, just that there are forces and motions that are not understood.
