http://en.wikipedia.org/wiki/Higgs_bosonThere are rumors flying that the Higgs Boson has been discovered at the LHC.
The Higgs is the final piece of the Standard Model of Particle Physics which is, itself, the crowning achievement of subatomic physics. Called the "God Particle" by some, the Higgs is responsible for giving all the other flecks of matter in this Universe the remarkable property we think of as mass. Physicists have been hunting the Higgs for decades. One of the main reasons for building the billion dollar LHC was to find the Higgs and determine its properties.
