When Vader and I whip out lightsabers , the blades look like sticks of light - matter . Light usually ' n't come together like regular matter , but scientists have made it together . You can shoot two lasers at each other , and the photons will pass right through one another . The new light - matter looks like it does in the movies , scientists say . But they have only created subatomic pieces of it , not nearly enough for a lightsaber .
