The Future Circular Collider (FCC) study develops options for potential high-energy frontier circular colliders at CERN for the post-LHC era. Among other things, it plans to look for dark matter particles, which account for approximately 25% of the energy in the observable universe. Though no experiment at colliders can probe the full range of dark matter (DM) masses allowed by astrophysical observations, there is a very broad class of models for weakly interacting massive particles (WIMPs) in the GeV – tens of TeV mass scale, and which could be in the range of the FCC.
Wild guess: they hacked the maths of those models/choose the models in order to fit the energy range of this new collider ? Ask Sabine H., need a BS meter evaluation... :)
This. If you want someone with honest insight into high energy theory, you probably shouldn't listen to a person who still pushes out papers that favour MOND over DM by curve-fitting special galaxies. This topic has been studied to death and it simply doesn't work well enough to warrant such strong opinions against DM. That's why her papers mostly go ignored in the community (many of them aren't even physics anymore and edge more into philosophy-babble or even sociology). All they do is make captivating conspiracy youtube videos for the average layperson.
You seem to have mistaken this fact for an opinion (all too common for her followers unfortunately). Fortunately, you can easily look up everything I said. But sorry, I don't have time to make brainrot youtube videos for people with no relevant education and no attention span. If you didn't know these things before, you also won't learn them on youtube. And I actually still have real work to do.
Of course, this sole HN comment is worth ten times more than a famous person making scientific videos on the internet... BTW, I wonder where is her mondo-meter at (aka "stuff" vs "model fixing").
We all know she has many enemies in the academics since targetting its funding... you are more likely to be one of them than anything else.
One comment. No. Countless scientific papers that have boiled into an accepted picture? Absolutely. But you won't hear about them if you only listen to one source on youtube who makes videos for non-scientists. Instead you'll see conspiracy everywhere. Like here somehow.
You are in luck, this is exactly the sort of questions that accelerator designers like to answer. You can find the answers on the first 70 pages in volume 1 of the FCC feasibility report: https://cds.cern.ch/record/2928193 just the first
