Trying to explain the topology of the Universe is really complicated... for humans. But it clearly comes naturally to Zogg the Alien from Betelgeuse. In this 10-minute video, the plucky alien vividly describes how we could have a Universe which is flat and finite, but doesn't have an edge. How we could travel in one direction and return to our starting point, never bumping into the outside of the Universe.
What is the Universe expanding into? Nothing, it's just expanding.
