The Large Hadron Collider has restarted after a two-year hiatus for technological repairs, paving the way for what scientists hope will be an uncharted frontier in particle physics, NBC News reported. "It's fantastic to see it going so well after two years and such a major overhaul of the LHC," said Rolf Heuer, the director general of Europe's CERN particle physics center, in a statement on Sunday. The world's most powerful "atom smasher," the $10 billion machine was instrumental in discovering the long-theorized Higgs boson. Over the two-year hiatus, the giant machine was upgraded with more powerful magnets that will accelerate protons to nearly the speed of light.
