CERN’s plan for 100-km collider makes the LHC look like a hula hoop

The Large Hadron Collider has produced a great deal of incredible science, most famously the Higgs Boson — but physicists at CERN, the international organization behind the LHC, are already looking forward to the next model. And the proposed Future Circular Collider, at 100 kilometers or 62 miles around, would be quite an upgrade.
The idea isn’t new; CERNhas had people looking into it for years. But the conceptual design report issued today shows that all that consulting hasn’t
