Scientists are set to announce on Wednesday that they have enough evidence to show the “God particle” almost certainly does exist.
The discovery could go some way to answering fundamental questions about the universe.

• Researchers at the CERN complex are not ready to call the findings ‘a discovery’
• Scientists expected to show the existence of the Higgs boson particle without actually showing the particle itself
But researchers at the European Organization for Nuclear Research, or CERN are not ready to say they have “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 does not allow them to say it has actually been glimpsed.
It appears to be a fine distinction. Senior CERN scientists say that the two independent teams of physicists who plan to present their work at CERN’s vast complex on the Swiss-French border on Wednesday are about as close as you can get to a discovery without actually calling it one.
“I agree that any reasonable outside observer would say, `It looks like a discovery,”’ British theoretical physicist John Ellis, a professor at King’s College London who has worked at CERN since the 1970s, told The Associated Press. “We’ve discovered something which is consistent with being a Higgs.”
CERN’s atom smasher, the $10 billion Large Hadron Collider, has been creating high-energy collisions of protons to help them understand suspected phenomena such as dark matter, antimatter and ultimately the creation of the universe billions of years ago, which many theorize occurred as a massive explosion known as the Big Bang.
For particle physicists, finding the Higgs boson is a key to confirming the standard model of physics that explains what gives mass to matter and, by extension, how the universe was formed.
Rob Roser, who leads the search for the Higgs boson at the Fermilab in Chicago, says “particle physicists have a very high standard for what it takes to be a discovery” and thinks it is a hair’s breadth away.
Roser compared the results scientists are preparing to announce Wednesday to finding the fossilized imprint of a dinosaur: “You see the footprints and the shadow of the object, but you don’t actually see it.”
