European Center for Nuclear Research (CERN) scientists control computer screens showing traces on Atlas experiment of the first protons injected in the Large Hadron Collider (LHC) during its switch on operation at the Cern's press center on September 10, 2008 near Geneva, Switzerland. Scientists fired a first beam of protons around a 27-kilometer tunnel housing the Large Hadron Collider (LHC).
They hope to recreate conditions just after the so-called Big Bang. The international group of scientists plan to smash particles together to create, on a small-scale, re-enactments of the Big Bang. (KEYSTONE/AFP PHOTO / FABRICE COFFRINI/POOL)
