Let’s say you’re a Jedi, and you dropped an active lightsaber straight into the Earth. Would it really just go all the way through to the center of the planet? Certainly, gags on shows like Rick & Morty and Robot Chicken have had fun with the idea. These are just the kinds of “science” debates that nerds love to have. Even when the science regarding anything in the Star Wars galaxy barely qualifies as science. But recently, YouTuber Rocket Riley decided to tackle the question head-on, with a video titled “What Happens If You Drop A Lightsaber Vertically?” So watch down below, and find out the answer.
The video pretty much destroys the fantasy that a lit saber would burrow itself down into the center of the Earth and somehow blow it up. For starters, the hilt and battery would melt long before the saber ever even got close to the planet’s core. Also, one lightsaber is not even close to the equivalent of a Death Star beam. Even though they both use kyber crystal technology. A Death Star’s destructive force is maybe the equivalent of a million lightsabers. So Earth (or any planet) would not go the way of Alderaan just because a lightsaber made it all the way down. But it wouldn’t make it all the way down anyway.

Most importantly, the Rocket Riley video explains that all lightsabers automatically turn off when dropped to the ground. If a Jedi (or Sith) throws it and it’s still on, it’s because the user is utilizing the Force to keep pressure on the hilt. Otherwise, it just shuts off the moment it leaves its owner’s hand. We know, that’s not as fun as a laser sword just melting through rock like butter. But those are the actual Star Wars rules. That Rick & Morty episode is still pretty funny, though.
