In this episode of Star Warsologies, we talk to Karen Yu about lasers! PEW PEW!

This episode, we dive into lasers in Star Wars but it turns out that many of the examples are likely actually something else entirely - plasma! Though lightsabers are sometimes called laser swords, Karen breaks down the reasons that light / lasers simply wouldn't work this way. Same goes for the Death Star's mighty weapon. Somehow we also end up talking about repulsor vehicles, invisible tires, and a lot of other physics and engineering quandaries. Enjoy!
