In this Feb. 29, 2008 file photo, the last element, weighing 100 tons, of the ATLAS (A Toroidal LHC ApparatuS) experiment is lowered into the cave at the European Organization for Nuclear Research CERN (Centre Europeen de Recherche Nucleaire) in Meyrin, near Geneva, Switzerland. ATLAS is part of five experiments which, from mid 2008 on, will study what happens when beams of particles collide in the 27 km (16.8 miles) long underground ring LHC (Large Hadron Collider). ATLAS is one of the largest collaborative efforts ever attempted in the physical sciences. There are 2100 physicists (including 450 students) participating from more than 167 universities and laboratories in 37 countries. (AP Photo/Keystone, Martial Trezzini, FILE)
