The new head of Cern, the world's premier particle physics laboratory, has a plan that will turn off one of its most powerful machines for years - a move that some are questioning as potentially holding back progress in the field.
Professor Mark Thomson, the 56-year-old Cambridge professor who takes over as director general of Cern next month, is about to embark on five years of overseeing the LHC's shutdown, replacing it with new superconducting magnets and detectors designed to squeeze protons into smaller, brighter beams. By June, the upgrade will make way for a new high-luminosity collider that promises even more precise measurements, potentially revealing new physics secrets.
However, one pressing question on everyone's mind - including Thomson's own scientists at Cern - is what comes next after the LHC reaches its end-of-life around 2041. The proposed Future Circular Collider (FCC) would be three times larger than the current machine and will require a massive investment of time, money, and international cooperation.
While some see it as an exciting new chapter in particle physics research, others are more skeptical about the project's ambition and its potential to answer fundamental questions in physics. One such mystery remains unresolved: why Higgs bosons gain varying masses, and how they interact with one another.
Thomson concedes that while the LHC upgrade will be a significant undertaking, Cern must press on, driven by "a passion for understanding the universe at its most fundamental level." But whether the high-luminosity LHC will unlock new breakthroughs remains to be seen. As the debate rages on over the feasibility of the FCC, one thing is clear: science at Cern has always been about pushing boundaries and taking risks - now more than ever.
