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 matt

- strbean 6y agoMOND 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.
- 8note 6y agoAre they changing f=ma though? Or F=Gm1m2/r^2? As far as I know, the mond models still require something equivalent to dark matter in order to work
