CERN Begins Building Giant Particle Accelerator.

Europe's CERN laboratory has begun the first steps towards building a new particle accelerator, the Future Circular Collider (FCC), which would be more than triple the length of the Large Hadron Collider (LHC). The FCC would form a new circular tunnel under France and Switzerland, 91 kilometers long and about five meters in diameter. The goal of the FCC is to push the energy and intensity frontiers of particle colliders, with the aim of reaching collision energies of 100 tera electron volts, in the search for new physics.
