"Bang" Up Idea

A European Center for Nuclear Research (CERN) scientist controls a computer screen monitoring the Atlas experiment of the first protons injected in the Large Hadron Collider (LHC) during its switch-on operation at CERN's press center on Wednesday, Sept. 10, 2008, near Geneva, Switzerland. Scientists fired protons around a 17-mile tunnel housing the LHC hoping to recreate conditions just after the so-called "Big Bang."
