Scientists Make Photons Behave like Lightsabers

by Rachel Baker on October 2, 2013

Research and technology have once again allowed science fiction and reality to occupy the same plane of existence.

Harvard and MIT physicists writing in the new edition of Nature say they have discovered a way to bind photons together in order to form a new molecule which behaves almost exactly like George Lucas’s deadly devices.

“Most of the properties of light we know about originate from the fact that photons are massless and do not interact,” said Harvard university physics professor Mikhail Lukin. “What we have done is create a special type of medium in which photons interact with each other so strongly that they act as though they have mass, and bind together to form molecules.
