"Europe's Ambitious Plan for a Massive Next-Generation Particle Collider"

CERN is proposing to build the Future Circular Collider (FCC), a particle accelerator three times longer than the Large Hadron Collider (LHC) in a 27-kilometer tunnel near Geneva. The FCC aims to address fundamental questions about dark matter and antimatter by smashing subatomic particles together at 100 teraelectronvolts, surpassing the LHC's energy level. The project, estimated to cost $21.5 billion, has sparked debate among scientists about its potential to generate new insights. If approved, the FCC could be operational by the 2040s, coinciding with the end of the LHC's useful life.
