A scientist smiles in front of a computer screen showing the first collisions pictures at full power at the Compact Muon Solenoid (CMS) experience control room of the the Large Hadron Collider (LHC) at the Large European Organisation for Nuclear Research (CERN) in Meyrin, near Geneva March 30, 2010. Scientists at the CERN research centre will begin trying on Tuesday to make particles collide at ultra-high power and close to the speed of light to create mini-versions of the "Big Bang" that gave birth to the universe.
