Overview

• CERN's feasibility study confirms no technical obstacles to building the Future Circular Collider (FCC), a $17-billion project to replace the Large Hadron Collider by 2041.
• The FCC would span 91 kilometers under the French-Swiss border, achieving energy levels of 100 trillion electronvolts, far surpassing the LHC's capabilities.
• The project aims to address fundamental questions about dark matter, dark energy, antimatter, and other unresolved scientific mysteries.
• Environmental groups and local communities have raised concerns about land use, energy consumption, and climate impact, while CERN has proposed mitigation measures.
• CERN's member states must decide by 2028 whether to approve the FCC, with construction planned to start in 2033 if funding is secured.
