What I was trying to ask is this: Let's assume you are standing at the "edge" that you mentioned. What would you "see" if you looked outward?

You are standing on the edge now. You can't look outward, only across the universe. If you could look "infinitely" far, you would see the back of your head.

Well, then that “loop of vision” where I am going to see the back of my head while I look ahead, is bounded, isn’t it? What’s giving it a boundary, and what is the expanse of the same?
