Large Hadron Collider

The Large Hadron Collider -- a huge machine in Switzerland and France that smashes subatomic particles together -- has begun operating. According to an article in the, protons "were whipped to more than 99 percent of the speed of light and to record-high energy levels of 3.5 trillion electron volts apiece raced around a 17-mile underground magnetic track outside Geneva a little after 1 p.m. local time. They crashed together inside apartment-building-size detectors designed to capture every evanescent flash and fragment from microscopic fireballs thought to hold insights into the beginning of the universe."
