CERN Report Confirms Feasibility of 56-Mile Particle Collider

CERN confirmed no technical barriers to building the $17 billion Future Circular Collider (FCC). Director Fabiola Gianotti stressed its importance for Europe’s physics leadership amid rising competition from China. A feasibility study supports a 91-km (56-mile) tunnel under the French-Swiss border, over three times longer than the LHC, which confirmed the Higgs boson.

With the LHC set to retire by 2041, CERN is planning ahead. Gianotti highlighted that “no technical showstopper” had been found. Catherine Biscarat of Toulouse University’s L2IT lab called the FCC “rich in possibilities,” essential for advancing research on the universe’s origins and the Higgs boson’s role.

However, concerns remain. The FCC’s estimated $16.9 billion cost has drawn skepticism, particularly from Germany, CERN’s largest contributor. CERN spokesperson Arnaud Marsollier reassured that up to 80% of expenses could be covered by existing budgets.

Locals and environmental groups have also voiced opposition. French dairy farmer Thierry Perrillat fears losing five hectares of his land, comparing the situation to “David and Goliath.” Environmental organizations criticize the project’s electricity consumption, climate impact, and scale.

Local Concerns Grow Over FCC’s Impact on Land and Resources

In Marcellaz, near a proposed surface site, activist Thierry Lemmel questioned whether the project justified such a large investment given its uncertain results. Some residents, like Kevin Mugnier, felt “stunned” after learning how the FCC could affect their property.

Others see benefits. Ferney-Voltaire’s mayor, Daniel Raphoz, supports the project, citing job creation and the potential to use CERN’s excess energy for heating. He warned that if Europe does not proceed, China will, risking European scientific decline.

CERN’s member states must decide by 2028 whether to fund the FCC, a project that could redefine the future of particle physics.
