This undated image made available by CERN shows a typical candidate event in the search for the Higgs boson, including two high-energy photons whose energy (depicted by red lines) is measured in the CMS electromagnetic calorimeter. The yellow lines are the measured tracks of other particles produced in the collision.

GENEVA -- Scientists working at the world's biggest atom smasher near Geneva have announced they are confident that the new subatomic particle discovered last summer is a version of the long-sought Higgs boson. The particle bears key attributes of the so-called "God particle" that was theorized nearly a half-century ago as fundamental to the creation of the universe. It took thousands of scientists from around the world to hunt the particle in the atom-smasher operated by CERN, the European Organization for Nuclear Research.

What Exactly is the God Particle?

Everything is made of atoms, inside of which are electrons, protons and neutrons. And those, in turn, are made of quarks and other subatomic particles. Scientists have wondered how these tiny building blocks of the universe acquire mass. Without mass, the particles wouldn't hold together - and there would be no matter.
