Most important is still the CMB. Back then everything was ionized and yet we have extremely good evidence of matter that only contributed gravitationally to density perturbations and not via the ordinary electromagnetic path. There is no way to explain this merely by modifying the law of gravity. So even if MOND or similar approaches turn out to be correct, they can never explain all aspects of dark matter. Only particles can. |
