(Newser) – The Large Hadron Collider roared to life today for the first time since September 2008. "The first tests of injecting subatomic particles" took just a fraction of a second, a CERN rep said, but the circulation of the proton beams confirmed that the repairs instituted 9 days after the collider opened were successful. "If all goes well tonight we will try to circulate a beam of particles for several minutes" early tomorrow morning, the rep said.
