Reposted by Mary SlipperWilliam Barter @wjbarter.bsky.social · 28/07/2026No other experiment can access the same details about the subatomic universe as LHCb, and no other experiment is likely to until the advent of the proposed future FCC-hh collider in the 2070s. Cutting LHCb will push back science by fifty years. 095

Reposted by Mary SlipperHarry Cliff @harrycliff.bsky.social · 07/07/2026Not only are these cuts damaging for UK science, they make no financial sense. We pay the CERN subscription to access amazing facilities like the LHC. Cutting funding for the experiments reduces the science we get out for each £ invested. It’s like building a railway line but not funding the trains. 112
