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.
I would be surprised. Quantum Gravity becomes relevant in very extreme energy conditions, while dark matter is relevant in the normal universe.
That sounds like it’s trying to take large scale phenomena and make them work on the quantum scale. What if the solution is the other way around: make modified quantum mechanics work on the large scale? (I guess those are effectively the same thing. You’d need a quantum gravity theory one way or another. Sorry, layman here. Just spitballin’ ideas)
