“the universe would expectedly make attempts to kill your grandfather exaggeratedly difficult to an almost cartoonish degree. The laws of probability would skew toward preventing the event from taking place, so anything that could go wrong in your attempt to kill your grandfather most likely would. The event with the highest probability would be you giving up out of sheer frustration your attempt to kill your grandfather.”
