Summary

In 1957, Hugh Everett III, a graduate student at Princeton, invented the concept of 'relative state', which would later be called many-worlds interpretation. As a result, we no longer have to worry whether Schrodinger's cat is dead or alive. Even if observations are made, the wave function does not collapse. We now understand that dead cats and live cats will exist separately in different universes. * This Documentary drama is the story of people who have experienced the parallel world.
