I often wonder what the edge of the universe is like, assuming there is one. If I were to travel in a straight line, would I eventually reach the edge of everything. What would be beyond the universe? Would there be anything beyond it? One researcher suggests that the universe is shaped like a soccer ball. It doesn’t answer what is beyond the edge, but it does make for an interesting theory. Assuming that the universe is actually round shaped, if I were to travel in a particular direction, would I eventually bend with the universe, so that I would constantly be on the edge. A better image may be to think of a hamster in a hamster wheel. He constantly travels in one direction, but the wheel moves under him. Of course, I still like the Danger Mouse idea that when you find yourself outside of the universe, you merely draw a new square on the map and poof you’re back in the universe.
