no. 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.
