I did read a super-awesome short story once though where a person creates a species of self-replicating nanobots that don't interact with anything unless they're told but rather just sit there after they've replicated, so they spread out through the universe starting from the origin, and get this, this is insane, the creator was able to use them to create a "force" like in Star Wars, so essentially if he wanted to manipulate things telekinetically on the moon, he could, how rad is that?
