I just tried to fight my way through the Palpatine article on Wookieepedia (which is really scary btw) and I think I read something like that his force storm power creates wormholes and he blew up a planet with it once.
It might have been that the planet was actually Nick Fury, idk, the article is somewhat unmanageable.
