No. Dark matter is a proposed form of matter which does not interact with light.
Normal matter we can't detect isn't dark matter - it's just currently undetected matter. As our observational ability improves we find more of it.
- whatshisface 2y agoThat's WIMPS, early candidates for dark matter included primordial black holes and dust.
- MattPalmer1086 2y agoA good point. I have heard of primordial black holes as a candidate for (at least some) dark matter. Not heard that dust was ever a candidate (if you have a reference it would be appreciated).
- petre 2y agoWIMPS are most probably not real. They'll keep searching but it's quite unlikely they'll find any. https://en.m.wikipedia.org/wiki/LZ_experiment https://en.m.wikipedia.org/wiki/LZ_experiment
- kelseyfrog 2y agoDark matter is a question, not a theory. WIMPS, sterile neutrinos, SIDM, primordial blackholes, MACHO, MoND, entropic gravity, &c all seek to answer the black hole question.
- ahazred8ta 2y agoBaryonic (tangible) dark matter exists in the form of MACHOs, which includes small cold planetary-mass dwarf stars. But there's a limited number of these, and the Big Bang hydrogen helium ratio puts limits on the amount of baryonic matter there can be.
