The Role of the Universe in the Multiverse

We are still trying to figure out which universe we are in. We don't really know what the rules of the universe are. All we can do is turn our heads skywards and gather the information that it sends us. By looking at photons and other particles that arrive on earth we get little bits of information, little clues that tell us what's happening out there in the universe. They tell a really fascinating story but one that we are still unraveling.
