How far away is the edge of the universe

We have not observed an edge to the universe. As we build bigger or more sensitive telescopes, we seem to see farther and farther.

Try this book or the web site with the same name:

"The View from the Center of the Universe"

It discusses these ideas without math overload.

(1) The universe as a whole has no edge.
(2) The /observable/ universe is not the whole universe.
(3) The edge of the observable universe is about 46 billion light years away, in all directions. (That is in terms of the "comoving" distance.)

As far as you can see.

There is no edge to the universe.

Quite a bit. You planning to go there?
