Wow, we are getting about 10 or so emails and comments a day about the LHC – most leading up to last night was how the world was going to end, and now they’re starting up again on how the world is going to end again in a month or so. I tend to think these people want the world to end.
Scientists have hailed a successful switch-on for an enormous experiment which will recreate the conditions a few moments after the Big Bang. They have now fired two beams of particles called protons around the 27km-long tunnel which houses the Large Hadron Collider (LHC). The Â£5bn machine on the Swiss-French border is designed to smash protons together with cataclysmic force. Scientists hope it will shed light on fundamental questions in physics. The first – clockwise – beam completed its first circuit of the underground tunnel at just before 0930 BST. The second – anti-clockwise – beam successfully circled the ring after 1400 BST.
