There has been work done toward re-working our current laws to fit observation without dark matter, but I think it just breaks way more stuff than it solves. The new model ends up being a worse fit for pretty much everything else but the galaxy rotation thing.
We already have weakly interacting particles like the neutrino, which don't interact with matter outside of the weak force, making them rather difficult to detect, it's not really that far out of the realm of possibility to have other particles that only interact via the gravitational force.

This is often mentioned as a reason not to spend time with alternative models. However, breaking stuff is sometimes necessary if we are to get out of the local maximum of theory usefulness. The Kopernik model was much worse fit for the observations of planet motion that the Ptolemy's model, but it did have other virtues, like simplicity. The broken parts got fixed later with development of mechanics and perturbation theory.
- Neeek 9y agoThat is a given. Dark matter isn't really that clean either, it breaks what we know about the standard model and known particles, something that the folks at CERN keep confirming as they break in to new and uncharted areas of what we can observe experiment. Your statement is less enlightening as it is simply stating the inaccurate nature of a model.
