This is my first post(Oh, second post. =P) here. I usually lurk the boards because I feel I don't know enough about the topics here to discuss anything. This one thing has been bothering me. I've read before that when we obverse things in space we are not seeing them as they are now, but as they were in the past. So, say we observe a random galaxy that is 1.5 million light years away. We are seeing it 1.5 million years in the past, right? So if we were to go to that galaxy, it would look nothing like as we were observing it from Earth? Wouldn't it be possible that life could have evolved in that galaxy? We wouldn't be able tell since we're observing it in the past. I'm not entirely sure if I'm perceiving this correctly or not. If someone could explain it to me I'd appreciate it alot.
