[QUOTE=Omnimancer;16738145]if gliese 581d got destroyed this very second from a black hole or something then we wont know that it was destroyed because it takes light 20 years from gliese 581d to reach earth so it means if it got destroyed right now we would know 20 years in the future[/QUOTE] And we'd notice any black hole anywhere near it before it arrived. Not that black holes just go wandering about throughout the galaxy, anyway. And if a nearby star that was heading towards the system was a likely candidate for a black hole we'd have noticed that too by now as, like the idea of its own star going nova, we'd start picking up strange energy outputs from nearby stars decades, even centuries before they finally went and blew up. Stars take a long time to anything, they don't just spontaneously go from a relatively cool star to a black hole in the snap of a finger. It's a long, long process.
