@rmcpherson I am not defending MOND or attacking dark matter. I am stating based on what they have said, it doesnt make sense unless they provide some basis on why its problematic for MOND
- jsweojtj 9y agoConsider galaxy 1, from visible matter, we might expect rotation curve A, but we see curve B. Explanation 1: MOND -- modified gravity at that scale, just works differently than we guessed. Explanation 2: Dark Matter Now this is galaxy 2, and from visible matter, we expect rotation curve B, and we get rotation curve A! So no, if it's just visible matter interacting w/ a modified version of gravity, it should predict consistent rotation curves. But we see two types. Thus it is directly problematic for MOND.
