The Problem With General Relativity

There's no point saying one believes in MOND, modified Newtonian dynamics. It doesn't matter if you're a physics professor who believes in it. That lends no credence to whether or not MOND is correct. Almost all observations ever made anywhere in astronomy are consistent with general relativity. What we've got at the moment with respect to dark matter are anomalous observations and, and otherwise, good explanation, general relativity. A false theory of gravitation, perhaps, pointing to a new explanation? I don't know. No one does. But we should expect these situations to arise - problems with existing theories.
