| Thanks for clarifying, much appreciated.

| Almost all accelerators built at CERN are still active and are
| a chain of pre-accelerator for LHC now:

| wow. Amazing map. Just imagine Half Life map with it... :)

| _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

| ? Ask Sabine H., need a BS meter evaluation... :)
| layer8 wrote:
| Sabine H. isn't exactly low on the BS scale.

| 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.
