The Future Circular Collider (FCC) is a proposed $30 billion project by the European Organization for Nuclear Research (CERN). It involves a 91 km circular tunnel beneath the Swiss-French border to accelerate and collide particles at record energies. Phase 1 (~2040) aims to generate Higgs bosons in large numbers, while Phase 2 (~2070) will collide protons at extreme energies. Supporters, including CERN leadership, call it the most powerful tool for studying nature. Critics argue it may drain funds, limiting investment in other scientific advancements. The project has sparked major divisions in the scientific community.
