Imagine travelling a very long way in space only to return just where you started, but upside down. Or consider living in an exotic donut-shaped universe, or one with far more than our usual three dimensions. The amazing thing is that we very well may. Today we’re joined at The Star Spot by Paul Sutter who will explain the crazy possibilities for the shape of our universe.
