"Seeing past the edge of the universe" is kind of an absurd idea in several ways.
First, space is what we call what's between things, so there is no space beyond the universe.
Secondly, "the Universe" in its usual meaning is an all-encompassing concept, such that if we looked beyond what we thought was our universe and saw something else, by the meaning of the term, THAT would also be part of our universe.
Also, I'm not following your logic in terms of the sphericity of the universe. Imagine we are inside a glass ball. Our biggest problem will be that there won't be anything to see beyond the ball. This looking back at ourselves thing is something you'll need to explain a bit more.
