Physicists edge closer to 'God particle' discovery (+video)
Scientists in Europe and the United States indicate that they have strong evidence for the existence of the so-called God particle, the Higgs Boson, which, if discovered, would help explain why matter has mass.
American scientists have found strong hints that the rumored Higgs boson particle exists, and has been created inside an atom smasher in Illinois.
"This is a very exciting week — it may be the most exciting week in physics since I became a physicist," Joe Lykken, a theoretical physicist at the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Ill., said during a news conference today (July 2).
The Higgs boson, also called the "God particle," is thought to explain why other particles have mass. The idea is that a related energy field, called the Higgs field, permeates space, and that as particles pass through this field their interactions with it confer mass on them, like a spoon being dragged through molasses.

Fermilab scientists announced today that they've narrowed down the possible range of masses the Higgs particle can have, if it exists, to between 115 and 135 gigaelectron volts (GeV), a unit roughly equivalent to the mass of a proton.The findings are the result of a long and thorough analysis of particle collisions inside Fermilab's Tevatron accelerator. The machine, the biggest atom smasher in the United States, was shut down in 2011, but scientists are still poring through its measurements.
