GENEVA (AP) -- Scientists working at the world's biggest atom smasher plan to announce Wednesday that they have gathered enough evidence to show that the long-sought "God particle" answering fundamental questions about the universe almost certainly does exist.
But after decades of work and billions of dollars spent, researchers at the European Organization for Nuclear Research, or CERN, aren't quite ready to say they've "discovered" the particle.
Instead, experts familiar with the research at CERN's vast complex on the Swiss-French border say that the massive data they have obtained will essentially show the footprint of the key particle known as the Higgs boson - all but proving it exists - but doesn't allow them to say it has actually been glimpsed.

It appears to be a fine distinction.
