Future SpaceHave you ever read an exciting book about the end of the universe or seen a video with fascinating pictures? It’s pretty exciting, isn’t it? We don’t know if it’s possible for us to travel between universes – but we do know that some galaxies that were once part of our universe are now traveling to other universes! The diameter of the observable universe is the same, no matter how we look at it, because the fact that the universe is 13 billion years old gives us the maximum diameter of the universe. So what do we see when we look at this galaxy 47 billion light years away from us? Looking back, we see the Milky Way, the universe in which we live. But what else – questions about questions.
