LHC fired up this morning Answered
At 7:00 GMT this morning, engineers fired the first beam at the Large Hadron Collider.
It worked on the first try.
We're not dead.
They didn't discover extra subatomic particles previously unknown to scienceyet.
Pretty boring, really.
Actually, apparently they had technical difficulties the night before-part of the cooling system (which keeps the magnets cool. Very cool. 1.9 degrees kelvin, to be exact.) failed. They worked on it and managed to fix it overnight though.
