I find it funny that there is no outside.
It is a wise man who can imagine a stick with no ends.
Steven I bet you have a formula for a stick with no ends.
Alex,

The best I can do is to give the topological edge equation of a one sided sheet of paper.

If you are on the outside of this Universe you must be at a higher dimension than this Universe. An analogy is the surface of a ball embedded in 3-D space.
If the observer however exists in the same dimension as the Universe, in your example the surface of the ball, there is no outside.
