We do observe dark matter though, just not directly through the electromagnetic spectrum. Much as the first extrasolar planets were found through deviations in stars' movement before we first imaged them.
- dnautics 5y agono. We infer dark matter. To use gravitation to say "there might be dark matter" and then later say 'dark matter exists because we see gravitational anomalies' is begging the question.
- colordrops 5y agoEverything is infered. That's why pretty much every scientific model eventually gets overturned or at least refined.
- dnautics 5y agono, you can deduce a new observation that is then observed. In the case of dark matter, this would most convincingly take the form of a multimodal observation. Predict that X particle is DM. It then has interaction Y that isn't gravitational. Then Y, which we were not looking for yet, is found.
