I mean, to find out about something like that. Like, we see light from thousands of years ago with our telescopes and satellites. What if we just suddenly picked up an intergalactic war off somewhere out there that happened. I mean, all those explosions have to give off a detectable amount of light - even light years away, right?
What would you do if you turned on the news and saw that astronomers had discovered something of that sort? Just how would you react?
I think it would instill a new hope in me for real...
