Topic: One step closer to a real lightsaber

Apparently scientists believe they can crystallize photons. Photons are subatomic particles which compose light. Crystalized ones would have the properties of a solid. So if you stick enough photons together in a shape (eg, a stick), they might give off so much heat energy they could melt things.
So lightsabers may be real in a few decades.
