Okay this rumor is all about the Large Hadron Collider on the French-Swiss border. Today is the first day that it has ever been used (it just successfully did its first experiment about 1 hour ago). By creating hundreds of thousands of head-on collisions each second with this machine, physicists hope to understand the fiery conditions of the universe a trillionth of a second after the big bang. The findings could also help resolve some of the biggest mysteries in physics, such as the existence of one long-hypothesized particle called the Higgs boson—or the "God particle"—thought to be responsible for giving all other particles their mass. Some people are worried that the experiments could also create unwelcome discoveries, such as particles and other exotic phenomena that could swallow up Earth or destroy the universe as we know it. For instance, one possibility is that the collisions will pack matter together so tightly that it may collapse to form miniature black holes, and that is where the rumor is coming from.
