I like Occam's razor as much as anyone, but it really is starting to seem like there might be more than one cause of the phenomenon called dark matter. My understanding is that WIMPs (weakly-interacting massive particles) are in trouble too, as the LHC has failed to produce them in the expected energy regimes.
- chorsestudios 3y agoOr perhaps it is more evidence that a variant of MOND theory is responsible for our observations and there is no dark matter.
- slowmovintarget 3y agoNo current MOND theories account for the state of our observations of the Cosmic Microwave Background, or the ratios of "things" left from nucleogenesis. The biggest gotcha for MOND is there's no way to reverse the direction of gravity, which would be needed to explain large scale structures without dark matter. (With dark matter, you see things moving toward where the matter is. Absent dark matter, you see things moving away from where matter is, because there is only ordinary matter.)
- SAI_Peregrinus 3y agoMOND theories are dark matter theories. They posit explanations for the observed behaivor, that behavior is dark matter.
- bashinator 3y agoAFAIK there are plenty of observations that can't be accounted for by any MOND theory either.
