As Marty McFly watches simultaneous television shows through his “Vidglasses”, today we see AR as a modern entertainment platform. Tom Cruise in Minority Report demonstrated several modern technologies including a holographic user interface. Swift swiping gestures and holographic touch screens help this character solve a crime in the film.

Heaven, Hell, Olympus, and Valhalla are all "alternative universes" different from the familiar material realm. Plato reflected deeply on the parallel realities, resulting in Platonism, in which the upper reality is perfect while the lower earthly reality is an imperfect shadow of the heavenly. The lower reality is similar but with flaws. The concept is also found in ancient Hindu mythology, in texts such as the Puranas, which expressed an infinite number of universes, each with its own gods. Similarly in Persian literature, "The Adventures of Bulukiya", a tale in the One Thousand and One Nights, describes the protagonist Bulukiya learning of alternative worlds/universes that are similar to but still distinct from his own. ![]() ![]() One of the first science fiction examples is Murray Leinster's " Sidewise in Time", in which portions of alternative universes replace corresponding geographical regions in this universe.
