First question:
It's estimated that the Milky Way Galaxy is about 13.2 billion years. If an observer was there 13.2 billion years ago looking out into space would he have seen the same distant galaxies that we can see now, which some people say are 13.7 billion years old?
Quote: Taking a closer look at the XDF (see a larger version), there are lots of spiral galaxies (similar to our own Milky Way), red galaxies (the remnants of galaxy collisions, which were much more common when the universe had first formed), and tiny dots that are mere galaxy seedlings. Remember, the XDF peers 13.2 billion years into the past, to when the universe was just 450 million years old. Today, 13.2 billion years later, the galaxies will look completely different — they will have moved apart, some will have ceased to exist, and the seedlings might have grown into full-blown galaxies.

You're still missing the point. If the Milky Way Galaxy is 13.2 billion years old that means that it's about the same age of the Universe, according to a popular theory. Some people conclude that the Universe is 13.7 billion years old based on the speed of light from the most distant galaxies. So you have a paradox. If the farthest object is 13.7 billion years away and it's fully formed as a galaxy would you have been able to have seen it 13.2 billion years ago from the Milky Way? Remember, such objects are all around us so it's just not one object that we're talking about.
Don't forget: there are countless galaxies between us and the farthest ones.
So what do you think?
