The most coveted prize in particle physics - the Higgs boson - may have been glimpsed, say researchers reporting at the Large Hadron Collider (LHC) in Geneva.
The particle is purported to be the means by which everything in the Universe obtains its mass.
Prof Brian Cox, a particle physicist, and presenter of the BBC 2 programme Wonders of the Universe said the discovery is the most important point in physics for half a century.
