You're confusing the broad scale cosmological predictions of DM with explaining rotational parameters of individual galaxies.
Even so, there are predictions low-parameter DM models seemingly can't make, like: what percentage of galaxies have zero dark matter?
- isthatafact 3y agoIf you were to create any model of the universe, you would require it to have the correct (observed) percentage of galaxies without dark matter, right? You assert that it is impossible for a model of a dark matter dominated universe to "predict" galaxies without dark matter, but that is exactly what people are looking at here in a large scale cosmological simulation: https://arxiv.org/abs/2202.05836 https://arxiv.org/abs/2202.05836
