The idea of a multi-dimensional universe, or multiverse, has been around for a long time. Many ancient spiritual and metaphysical philosophies speak of multiple realms or planes of existence, going all the way back to ancient texts from Buddhism, Hinduism, and Kabbalah, among others. In recent times, the idea has gained traction and acceptance among scientists, taking it out of the domain of myth, lore, and science fiction into possible reality. Although at this point the notion of other realities bumping up alongside our own remains solely within the realm of theory, experimentation, and conjecture, there are some who have been claimed to have actually punched through the veil between dimensions and opened portals between them, bringing new debate and oddness to this intriguing concept.
