Bold push for new super-collider

The CERN Council — the body that oversees the European particle-physics lab — has given a strong, if preliminary, endorsement for the building of a 100-kilometre successor to the Large Hadron Collider. CERN hopes to raise €21 billion (US$24 billion) to build its new circular machine, starting around 2038. It would collide electrons with positrons to produce myriad Higgs bosons and dissect their finer properties. The tunnel could later be reused for an even more powerful proton–proton collider that could, in principle, discover entirely new particles. The machine won over competitors, including a linear electron–positron collider and one that would accelerate muons instead.
