It was September 10, 2008, when the world’s largest experiment, the Large Hadron Collider (LHC) started its operation. Located at CERN, the European Particle Accelerator Laboratory at the Franco-Swiss border near Geneva, the LHC particle accelerator resembles an enormous ring with a circumference of 27 km (17 miles), buried 100 m (328 feet) underground. When it runs at full power, the LHC is able to accelerate protons to a velocity that reaches 99.9 percent of the speed of light, so each particle attains an enormous kinetic energy. At regular time intervals and deep in the center of dedicated particle-detectors at specific places in the ring, the accelerated protons are forced to follow a course that ends in a head-on collision, which releases the kinetic energy in an event that resembles a “mini-Big Bang.”
