Buried beneath the grassy countryside near Geneva, Switzerland, is a giant tunnel in the shape of a circle 8.6 kilometers (about 5 miles) across. There, scientists recently discovered a particle they had been hunting for a very long time: something called the Higgs boson. It helps explain how everything in the universe has developed mass.
