Many Worlds Theory: You're in a Parallel Universe | Can You Visit Your Other Lives?

The "Many Worlds" or "Multiple Universes" theory says that anything that can possibly happen does happen. It just happens in a different reality that exists parallel to our own. Yes, some of these alternate realities are more far-fetched than others. But they are all out there. Scientists know how these realities are formed and people are working on technology to detect them. But even if we could detect alternate universes, there's no way to visit them. Or is there?
