They did it! MIT and Harvard scientists have created ‘lightsaber-like’ particles!

This sounds like a joke, but it’s not. A team of physicists were fooling around with photons when they managed to get the particles to clump together to form a molecule, one that’s unlike any other matter. And it behaves, they say, just like a light saber.

That’s right. Lasers were used to discover a new form of matter that’s straight out of a Star Wars film. Credit for the experiment goes to Harvard physics professor Mikhail Lukin and MIT physics professor Vladan Vuletic, who blasted photons through a cloud of rubidium atoms. When they sent more than one photon at once, they noticed that the particles clung to each other to form a molecule.
