Many hurdles remain
...the Higgs boson, the most elusive speck of matter in the universe. Often called the God particle, it's supposed to be the key to explaining why matter has mass. Physicists believe that Higgs particles generate a kind of soupy ether through which other particles move, picking up drag that translates into mass on the macroscopic scale. The Higgs is the cornerstone of 21st-century physics; it simply has to be there, otherwise the standard model of the universe collapses.
