First Technique to Turn Light into Matter Discovered

First Technique to Turn Light into Matter Discoveredfrom ndtv.com: In a breakthrough, scientists have for the first time discovered a revolutionary technique to turn light into matter, a feat thought impossible when the idea was first theorised 80 years ago. Three physicists at the Imperial College London's Blackett Physics Laboratory worked out a relatively simple way to physically prove a theory first devised by scientists Breit and Wheeler in 1934. Breit and Wheeler suggested that it should be possible to turn light into matter by smashing together only two particles of light (photons), to create an electron and a positron - the simplest method of turning light into matter ever predicted. The calculation was found to be theoretically sound but Breit and Wheeler said that they never expected anybody to physically demonstrate their prediction. It has never been observed in the laboratory and past experiments to test it have required the addition of massive high-energy particles, researchers said. The new research, published in the journal Nature Photonics, shows for the first time how Breit and Wheeler's theory could be proven in practise.
