No, dark matter is not a set of observations, but instead it's a hypothetical form of matter, invisible and weakly interacting except with gravity, employed to explain a set of observations.
- 8note 5y agoI don't think the weak interaction is required? Theres both theories for dark matter that include the weak force and that don't iirc? The only thing we know for sure is that we can define a field of masses that corrects for the difference between the observed behaviour and predicted behaviour of the cosmos vis a vis general relativity.
- Maursault 5y ago"Weakly interacting " does not mean the Weak Nuclear Force specifically. Dark matter only interacts with ordinary matter through gravity and does not interact through (or is vanishingly weakly interacting through) electro-magnetism, strong nuclear or weak nuclear forces.
