The Universe Expands Away From Us

In the far future, we wouldn't be able to see even the light from our closest neighbouring galaxy. In a universe that's not expanding, the observable universe grows by one light year in radius every year. There almost certainly is something out there, a galaxy so far away that light has not yet had time to get to us. Something happens on andromeda, which is millions of light years away, you don't see it immediately. And aliens living in another galaxy have a very different observable universe because light needs time to reach them.
