European physicists boldly take small step toward 100-kilometer-long atom smasher.

CERN’s governing council announced it will launch a technical and financial feasibility study to build an even bigger collider 80 to 100 kilometers long (actually two of them in succession) that could ultimately reach an energy seven times higher than the LHC. The first machine wouldn’t be built before 2040.
