      Endless and endless and endless. It goes on forever. Because of how space is shaped, you’d never reach the “edge” of the Universe. For example, if you set off from Earth in a super fast space shape, with the goal of just travelling in a straight line until you hit the edge of the Universe…

      …you’d end up back at Earth. Because the Universe curves. So in that way, it is endless 🙂
