But did you know that some of the stars that we see at night are already dead? It's just because it takes so long for the light to reach us that we can view as if it's a star whereas it may actually be a supernova.

in fact recently the farthest thing ever seen was seen. it was a gamma ray burst or something that happened 9.2 billion light years from earth, but because of the expansion of the universe it ended up traveling 13.1 billion light years to get here.
