Yes! This is the news I have been waiting for since I was six and first saw Obi-Wan and Darth Vader cross blades on the big screen. Harvard physics professor Mikhail Lukin and MIT physics professor Vladan Vuletic were experimenting with photons, and found that when the photons clumped together they formed a new type of matter similar to lightsabers.
“It’s not an in-apt analogy to compare this to lightsabers,” said Lukin in a press release. “When these photons interact with each other, they’re pushing against and deflect each other. The physics of what’s happening in these molecules is similar to what we see in the movies.”
It’s a phenomena that’s called Rydberg Blockade which apparently has nothing to do with that blockade above Naboo. The pair aren’t planning on making weapons, but instead hope that the discovery will help in building quantum computers.
