Scientists believe they have discovered a new sub-atomic particle that could be the Higgs boson.
Experts at the Cern research centre near Geneva, Switzerland, are confident they have caught sight of the so-called 'God particle', which lends mass to matter and holds the universe together.
The Higgs boson theory - proposed by British physicist Peter Higgs in the 1960s - suggests the existence of an invisible force field and associated sub-atomic particle that permeates all things, working like glue to give form to stars, planets and even humans.
Without the Higgs particle, the universe would have remained like a soup, the theory says.
In December last year, scientists at the Large Hadron Collider (LHC) - the 'Big Bang' particle accelerator which recreates conditions a billionth of a second after the birth of the universe - revealed they had caught a first tantalising glimpse of a boson
