How many Colliders around the world?

As of October 2023, there are several major particle colliders around the world, with the most notable being the Large Hadron Collider (LHC) at CERN in Switzerland. Other significant colliders include the Fermilab's Tevatron (now decommissioned), the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory, and various smaller facilities. In total, there are dozens of particle accelerators and colliders globally, but the exact number can vary as new facilities are built and old ones are decommissioned.
