Summary

When physicists at the European particle physics laboratory, CERN, reported last week that they had discovered the famed Higgs boson, or something much like it, it marked the first time since 1995 that a new fundamental particle had been unearthed. Particle physicists have apparently confirmed a decades-old prediction of how the universe works and found the last piece in their standard model of fundamental particles and forces, perhaps the most elaborate and precise theory in science. But the advance also leaves particle physics at a curious crossroads. If no new particles or phenomena show up, the discovery of the Higgs could mark the end of the road.
