In 1915 Albert Einstein produced a theory of gravity that allows us to describe whole universes. What is that theory, how does it work, why do we take it seriously, and what are these universes that it predicts can exist? We will look at some of the unusual universes that have been found to be solutions of Einstein?s equations over the past 90 years and discover which, if any, of them looks most like our own Universe.
