Ranga-Ram Chary, a cosmologist from Caltech, has discovered scientific evidence that could prove the existence of multiple and parallel universes. He found an anomaly in the cosmic microwave background that points to the possibility of pocket universes having been created with the expansion of the main universe itself.
