When Hubble stared at nothing for 100 hours (2015)
Since we seem to have a good discussion here, there's something I've always wanted to know.If I understand correctly, the universe is approximately 13.8 billion years old. As is mentioned frequently when staring at deep space, we are looking at the universe not as it is, but as it was, since it takes so long for the light to travel to us. Some objects in the Hubble Deep Field are over 9 billion years old, and some within 1 billion years of the beginning of the universe.My question, as best I am able to ask it, is assuming the big bang theory is true, how can it be that we on Earth can be looking at something simultaneously so old and so far away? If everything originated from the same point, how can it be that we pick an object in the sky and say "that is what the object looked like 12 billion years ago"? Doesn't it beg the question, "well then where were we 12 billion years ago?" As in, how can we be here, observing something close to the beginning of time? Didn't both objects start at the same  place?I hope that makes sense..
