What's that saying again? Extraordinary claims require extraordinary evidence? I don't think we're quite there yet, but for all of you MOdified Newtonian Dynamics fans (and Dark Matter haters) out there here's a bit of good news.

I just watched that video somewhat recently and couldn't understand that quote. There are a number of MOND models that literally don't involve dark matter at all -- no new particles added, no unexplained masses needed. So in that case, wouldn't "how we combine them" just be "set dark matter to 0 and use this different set of equations to solve for gravity in certain circumstances"?

The MOND models are less accurate than cold dark mater models. As long as MOND fails to explain current phenomina, cold dark matter wins. Period.

I am a fan of the idea that the standard model is incomplete/wrong, but you cannot in good conscience accept a model that fits the data worse all because the current best model has problems.

A proper answer explains why the current model works but is inaccurate. MOND models straight up disagree.
