It would be a spectacular triumph for CERN to produce a particle that might constitute the dark matter (like the WIMP you suggest). While possible, I consider this outcome to be unlikely.https://twitter.com/malnadi/status/1132847678663143430 …

But particles seems highly unlikely. If they are freely moving they would cause severe gravitational ”ghosting”, and if the interact among themselves, they need to mirror our universe?
That would assume that the interaction strengths in the Dark Sector are the same as in the SM which we know isn’t the case

Ok, thanks! Any chance of simulations that would show the thought interaction then at galaxy level? If I try to visualize it, it doesn’t add up.

One more question, if the gravitational interaction is lower for BM, and the 85% accounts for visible ”mass”. Then it would mean it could very well be 100-1000% of DM in proportion to visible matter? What size would DM particles have?
