GENEVA, SWITZERLAND - SEPTEMBER 02:  A general view of the XXX, part of the CERN LHC experiment on September 2, 2014 in Geneva, Switzerland. The European Organization for Nuclear Research (CERN), which has 21 member states, has built amongst other experiments the Large Hadron Collider (LHC). The world's largest atom collider has been investigating antimatter, dark matter and the creation of the universe. Built around a 27-kilometre underground ring of superconducting magnets where two high-energy particle beams travel at close to the speed of light in opposite directions before they are made to collide at four particle detectors.
