MIT and Harvard just made a real lightsaber. So that’s done.
-
Scientists at the lab are reporting that they’ve successfully managed to get two photons to interact with each other and form a “photonic molecule” that acts as if it has mass but maintains the properties of light. Photons as a rule contain no mass and don’t interact with each other, which is why two beams of light pass right through each other. Lightsabers aside, the creation of a “photonic molecule” is actually a Pretty Big Deal.
"An elegant weapon, for a more civilized age."

"managed to get two photons to interact with each other" That's some tiny lightsaber.

It's not the size, but in how you use it. :-O
