Our Universe is unimaginably big with billions of galaxies and stars in it. But is there anything beyond what we can see and know? Science fiction and even some scientists believe that there could be an infinite number of universes called parallel universes that exist alongside ours, with anything from small differences in events to entirely different rules of Physics! This idea has references in religion and mythology as well. As well as many movies and books like Spiderman, Dr. Who, Star Trek and others. Would you like to go meet yourself in another Universe?!
