Scientists at the Geneva-based European Organization for Nuclear Research believe they are honing in on the so-called God particle, also known as the Higgs boson. Scientists hypothesize that this particle is what allows other particles to have mass. Researchers at the institute, known as CERN, are using the 27-kilometer Large Hadron Collider to try to create the conditions that existed after the Big Bang that formed the universe 13.7 billion years ago. Alternative explanations for the mechanism that allows particles to have mass are also being pursued. Scientists working on the Higgs boson say they'll search for another year. If it is not found by then, they will conclude that it doesn't exist (Washington Post, December 13).
