The $22 billion gamble: why some physicists aren’t excited about building a bigger particle collider

CERN has proposed quadrupling the length of the world’s longest particle collider, laying out plans for a 100-kilometer tunnel under the Franco-Swiss border that would allow particle physicists to probe physics beyond what even the Large Hadron Collider, which produced the discovery of the Higgs Boson, would allow. But some physicists say it isn’t worth the cost.

“The scientific case is weaker than it has been for past colliders,” said Hertz Fellow Jared Kaplan, a theoretical physicist at Johns Hopkins University. “You’re getting further removed from relevance to technologies on a human scale.”
