CERN's Large Hadron Collider to Resume Smashing Particles in Hunt For Dark Matter

The Large Hadron Collider (LHC) will start smashing particles together at unprecedented speed on Wednesday, churning out data for the first time in more than two years that scientists hope might help crack the mystery of "dark matter". The LHC, a 27 km (17 mile) underground complex near Geneva, will smash protons at 13 tera-electron-volts (TeV), almost twice the energy achieved in an initial three-year run that began in 2010. This proved the existence of the elusive Higgs boson particle, a discovery that produced two Nobel prizes in 2013.
