Working on a theory to combine quantum mechanics with Einstein's special relativity, he realised his equations predicted a corresponding anti-particle for every particle in existence - identical in every respect, but with an opposite electrical charge.

Einstein's special relativity theory that says energy equals mass times the speed of light squared underlies "pretty much everything in modern physics, " said John Ellis, a theoretical physicist at CERN who was not involved in the experiment.
