CERN Council reviews feasibility study for a next-generation collider
- mikebonnell 11mo agoWould this be a different loop, but connected to LHC or is this a new standalone loop where they would need to find a locale to build it underground?
- elashri 11mo agoThis will be a completely new tunnel loop. The LHC tunnel will be used by LHC at the same time the new tunnel loop is being constructed.
- mikebonnell 11mo agoThanks for clarifying, much appreciated.
- maxnoe 11mo agoCompletely new tunnel, but it will be connected to LHC, as they will use LHC to pre accelerate the particles. Almost all accelerators built at CERN are still active and are a chain of pre-accelerator for LHC now: https://en.wikipedia.org/wiki/Large_Hadron_Collider#/media/File%3ACERN_accelerator_complex_2022.png https://en.wikipedia.org/wiki/Large_Hadron_Collider#/media/F...

- amanaplanacanal 11mo agoWhat experiments would people like to do, that this new collider would make possible? What theories will be tested?
- robin_reala 11mo agohttps://en.wikipedia.org/wiki/Future_Circular_Collider#Motivation https://en.wikipedia.org/wiki/Future_Circular_Collider#Motiv... 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.
- sylware 11mo agoWild 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... :)
- layer8 11mo agoSabine H. isn’t exactly low on the BS scale.
- sigmoid10 11mo agoThis. 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.
- UltraSane 11mo agoI think the money would be better spent on gravitational wave detectors as they might detect data about the true nature of black holes and help us develop a theory of quantum gravity or at least rule some out.
- bloggie 11mo agoThese experiments afaik don't require particle accelerators and are a different field of science, one of the largest of these detectors is the LIGO observatory overseen by Caltech https://www.ligo.caltech.edu/page/what-is-ligo https://www.ligo.caltech.edu/page/what-is-ligo There is a list of similar observatories in this document https://dcc-llo.ligo.org/public/0125/G1600979/003/G1600979_Lantz_SLACv3.pdf https://dcc-llo.ligo.org/public/0125/G1600979/003/G1600979_L...
- UltraSane 11mo agoI know. That is why I think the money that would be spent on a new particle accelerator should be spent on new more sensitive gravitational wave detectors.
- aeve890 11mo agojust one more accelerator bro. just one slightly larger accelerator than the one we just got online. we can revolutinize physics with just one more accelerator bro. Just give me 20 billion euros bro and we'll solve physics I promise br
