Where is the edge of the universe?
Assume you take a rocket ship to just outside the orbit of earth so you are in space with a clear view around you.
You look north. You see (hypothetically with your laser beam eyes) a galaxy 1 billion light years away. You think, ok well the universe is at least 1 billion years old.
Then you look south and see an object 13.8 billion light years away.
Then east, west, up and down. What do you see when you look down? Is the universe or edge of it even on all sides? Is there more universe on the west side? Where are we in relation to where things are expanding? Is there an object 11 billion light years to the east and another object 6 billion light years to the west? What does that mean for us and how old the universe is? Where is it expanding?
If the universe is expanding faster than c than it is infinite. But where is the edge? Expansion implies an edge because something is expanding into something. Does time not exists outside of the edge of the universe? If it was infinite, then how can it be expanding? The concept of expansion doesn’t make any sense within the realm of the infinite.
