    • It would get stuck at the hilt. If it had a hilt (handle) narrowerer than the blade then it would fall through the earth until it got to the middle of earth's core. It would bounce around inside the core for a few minutes, constantly falling "past" the gravitational centre of the planet until it eventually didn't have enough momentum to continue moving. At that point it would sit in the very middle of the planet forever. The hole it created on the way down would instantly close behind it (due to the pressure and molten rock). It'd be totally harmless and you'd have no way of knowing it was even there. Of course, a "real" lightsaber would get stuck as soon as the blade went through something solid in the ground (like a rock or even some wood) as the handle is wider than the blade. It'd be like poking a sword through a piece of cardboard - the whole blade goes through easily but the handle wouldn't let it go any further. If it did keep falling then after about 15-20 miles (25-40 kilometers) the liquid magma would simply melt the metal handle, which would mean that the complex components of the lightsaber would break and it would turn off forever very quickly. Lightsabers don't won't like in Richard & Mortimer Esq., unfortunately.
