Dark matter isn't theorized to necessassrilly be a particle either (finding new symmetries in the standard model would be extremely surprising)- it's literally just a placeholder name for a massive (as in, exhibits mass) unknown.
- roywiggins 9y agoDark matter theories absolutely do theorize invisible mass-bearing particles. https://en.wikipedia.org/wiki/Dark_matter#Composition_of_dark_matter:_Baryonic_vs._nonbaryonic https://en.wikipedia.org/wiki/Dark_matter#Composition_of_dar... It might be ordinary matter hidden from us somehow (maybe inside black holes) or something new like sterile neutrinos or WIMPs.
- pharrington 9y agoYes, one way to restate my post is that dark matter could or could not be a new particle. The important part is that dark matter proponents assert there is something(s) whose mass we can detect, but whose other properties we can't measure as it doesn't fit into our current physical models.
