You could say the same thing about the ether, the centrifugal force, and the argument about flat earth.
My money is on dark matter's effects being due to some as-yet-undetectable acclerative force, maybe due to deformative effects of gravity that are only apparent at massive scales. Some sort of extension of GR that takes into account local clustering of energy that it isn't yet doing. But I'm no cosmologist.
Is that what the cosmological constant is all about?
