Ok, but how much dark matter does MOND have? My understanding is that it just renames dark matter, but still can't describe gravity based solely on visible matter
MOND isn't a model, it's an umbrella for models that change `F=ma`. Seems like most MOND models still don't account for a large amount of observations, but it's probably worthwhile to compare the person-hours devoted to fitting dark matter models vs. MOND models, and give the MOND approach some benefit of the doubt.
