Want to imagine what it’s like to be in Billy Pilgrim’s place—who goes to sleep as an elderly widower and wakes up on his wedding day; walks into a door in 1955 and walks out in 1941; returns through the same door and finds himself in 1963; has seen both his birth and his death many times and keeps ending up in the events of his life already lived, between his birth and death? Nothing could be simpler: you only need to learn from the Tralfamadorians, who occasionally visit Earth in their flying saucers, to see in four (not three, like “sensible” humans) dimensions—and then you’ll understand that moments in time do not follow one another like beads on a string; they exist and will exist together in the same place. One piece of advice: when wandering through time, choose doors so you don’t accidentally end up at the slaughterhouse—No. Five!
