A proposed experiment may soon transform particles of light into matter.

Oliver Pike, a plasma physicist at Imperial College London, typically works on nuclear fusion — a process that converts matter into energy and not vice versa. But he and his colleagues laid out plans for a device that would use a key piece of fusion equipment to convert light, a form of energy, into particles with mass. It would do so by smashing photons together to create electrons and their antimatter counterparts, posi...
