- DagAgren 7y agoNot at all relevant, as we can see the effects of dark matter in many places, very clearly.
- layoutIfNeeded 7y agoSo you can detect it after all?
- Supermancho 7y agoWe're not sure it's matter, but let's just say 'dark matter' is a useful abstract label (like 'teapot'). We know that SOMETHING is perturbing our models that are useful (to simplify the analogy, let's just posit that newtonian orbits are casually affected, for example) by measurement. As much as an orbiting 'teapot' is ridiculous, it's also provable that something is unaccounted for, 'teapot' or 'dark matter', whatever the label. This does not mean that it's matter specifically (just a label), but is a phenomena.
- DagAgren 7y agoIndirectly, yes. Directly, not yet.
- layoutIfNeeded 7y agoDefine "directly". The definition of dark matter is that it's electromagnetically non-interacting, therefore observing it's gravitational effect is as direct as it gets.
- DagAgren 7y agoSince we do not know what exactly it is, defining "directly" is not really something you can do. But, for instance, electroweak interaction is being looked at, I gather?
