Shelton, from Big Bang Theory, believes in a multiverse. He means that there Ian an Multiple number of universes where multiples iterations of each of

each of us existed. Assume you could watch and control your behaviour in each of these universes. In a "real" multiverse situation you could not. Would you try to behave the same in all them or would you use one or more of the universes to experiment with your behaviour to see how to get out of tricky situations?
