Large Hadron Collider creates 'mini Big Bang' with lead ions - Telegraph: "The reaction created temperatures a million times hotter than the centre of the Sun, which have not been reached since the first billionths of a second following the Big Bang. This was expected to cause atomic particles such as protons and neutrons to melt, producing a 'soup' of matter in a state previously unseen on Earth.
Scientists, including British particle physicists, will now study the particles in the hope of discovering what holds atoms together and gives them their mass.
The collisions were produced by firing lead ions – atoms with their electrons removed – at incredible speeds in opposite directions around the LHC's underground tunnel at CERN, the European Organization for Nuclear Research, near Geneva."
