Planet bust should be visible to our technology. We'll spot one soner or later if colder war is still waged. Plus, it's much harder to cook the entire solar system and planet death isn't the end of the game.
- krapp 13y agoDidn't a rather large asteroid pass between the Earth and the moon recently, and no one even noticed it until it was on the way out? Just because something should be visible doesn't necessarily mean we'll happen to be looking at the right place at the right time within the right spectrum. There could be a lot we simply don't see.
- guard-of-terra 13y agoI mean that we should spot other homeworlds being busted across the galaxy.
- krapp 13y agoThere are billions of galaxies, though, and my point is we may still be half-blind, since we've only recently even able to detect exoplanets smaller than Jupiter IIRC. And, if we did see something, we would likely interpret it as a natural event. It would probably be in the best self-interests of whatever species launched an attack to make it appear like a natural event in any case, so as not to draw attention to their existence from unknown parties (like us.) And a collision that could wipe out a civilization is clearly within the realm of natural possibility since it's happened on Earth in the past (without the civilization part..) so it need not necessarily draw attention to itself.
