Part of the problem is that fixing Newton is more than just adjusting the equation; it requires making up a whole new constant, which to some is worse than making up a whole new class of matter. Constants don't have explanations; they're just like saying, "I don't know why it works out this way, it just does." It's better to have a reason that explains why something happens than to throw up your hands and say "let's just add a new constant to make things work out."
- jack9 10y agoA constant is a lot more constrained (existing in a specific context) than a class of matter that can't be observed, which is used as a hand wave to any measurement that is unexpected because not only is it not observed, it's not fully understood/constrained.
- dnautics 10y agoThat's not terribly convincing argument. Effectively MOND means adding a single free parameter to the model and dark matter means adding a entire continuous distribution to the model.
- wnoise 10y agoA new class of matter has a whole bunch of constants -- mass, interaction coefficients, mixing angles, etc.
