The toroidal Universe

This is a representation of the hypothesised toroidal Universe, or "donut theory" of the Universe. Such a Universe cannot really be visualised this way, as donuts have two dimensional surfaces, and the proposed toroidal Universe would be curved not just through space, but through spacetime. However, it is simpler, and also rather fun, to visualise our Universe as a sort of cosmic donut. This graphic will form part of the "The Living Universe" exhibition, to be displayed at the ESO Supernova.
