So the universe is expanding, and has expanded for ~14 billion years. As I understand it, the expansion of space has progressed at a speed that is greater than c. This is why when we point telescopes to some great distance we can see how the universe looked at an earlier stage of it’s development. Also, as I understand it, the reason earth isn’t flying away from the sun, and the sun flying away form the local group of stars is gravity. I picture it in my head like a bunch of people (stars) standing on a huge block of ice on the sea. As the ice breaks apart and begins to spread, people who were holding hands (gravity) will tend to stick together even as some other groups of people (galaxies) will drift away.
Assuming I’m right about all this, I have a question: Since space is expanding at a speed greater than c, shouldn’t we be able to see our OWN galaxy somewhere behind us as it was in the past? Couldn’t we (if we had a strong enough telescope) theoretically be able to see earth as it was in the past, just as we can see what early galaxies looked like?
