Real-World Chemist Explains What Lightsaber Colors Really Mean

A chemist has explained what Star Wars’most iconic lightsaber colors would mean in the real world. When the original Star Wars movie, later retitled A New Hope, first premiered in 1977, audiences were wowed by the magnificent blue and red laser swords wielded by Obi-Wan Kenobi, Luke Skywalker, and Darth Vader. Though the meaning behind each lightsaber color seemed relatively simple following A New Hope and The Empire Strikes Back, Return of the Jedi changed the game by introducing Luke’s green lightsaber.
