The Large Hadron Collider successfully passed its first test, and hasn’t launched the universe into a black hole:

An international collaboration of scientists today sent the first beam of protons zooming at nearly the speed of light around the world’s most powerful particle accelerator–the Large Hadron Collider (LHC)–located at the CERN laboratory near Geneva, Switzerland. The U.S. Department of Energy (DOE) and the National Science Foundation (NSF) invested a total $531 million in the construction of the accelerator and its detectors, which scientists believe could help unlock extraordinary discoveries about the nature of the physical universe.

What does the Large Hadron Collider do? Well, the Large Hadron Collider Rap drops some knowledge:
