The incredible discovery of the Higgs boson will open up new ways of probing the part of the universe that is invisible to our everyday senses: beyond ordinary matter, into the extraordinary world of dark matter. It isn't often that you get to be physically present at an historic occasion, I was at CERN on July 4 when scientists at the Large Hadron Collider announced the discovery of the Higgs boson particle. Hundreds of young physicists had camped out from the previous night just to get good seats at the technical seminars proclaiming the discovery. What we witnessed was the first solid evidence for the particle that explains how other particles like electrons and quarks get to be massive.
