[Starwars] If you drop a lightsaber facing directly to the ground, is it gonna burrow till it reaches the core of the planet?

Even if you bypass all safety features, manage to keep the blade activated and the saber angled correctly, this won't happen. 

That's because a lightsaber doesn't *delete* matter, it *heats* it. Some matter may be displaced to the sides but ultimately mass is conserved. You'll eventually end up a saber suspended in a thick gooey pool of magma that will stop growing when the energy output of the saber matches thermal dissipation of the surrounding environment.
