Large Hadron Collider Officially Begins Second Run
After a 27-month upgrade, the Large Hadron Collider is officially back in action, and physicists are hoping it will spot something brand new.By Steven Sparkman | June 3, 2015
With some fanfare and a whole lot of scientists on hand, CERN's Large Hadron Collider officially began its second run Wednesday, approaching a feat more than 20 years in the making.
The collider, famous for such headlines as the discovery of the Higgs boson and the conspiracy theory about a black hole apocalypse, was shut down in early 2013 to allow for a long series of upgrades.
The work involved painstakingly reinforcing thousands of small but important pieces of the 17-mile engineering marvel, with the effect of making the LHC almost two thirds more powerful than it was in its first run.
