When Billy is on the spaceship to Tralfamadore he asks for a Tralfamadorian book to read. The Tralfamadorians give him some, but tell him that he won't be able to understand them. The book is filled with pictures instead of words and they are all meant to be looked at, at the same time because then the message of the book will be clear. 

"There isn't any particular relationship between all the messages, except that the author has chosen them carefully, so that, when seen all at once, they produce an image of life that is beautiful and surprising and deep. There is no beginning, no middle, no end, no suspense, no moral, no causes, no effects. What we love in our books are the depths of many marvelous moments seen all at one time" (pg.88).

Slaughterhouse 5 was written so that all the moments are happening at once, and by the end all the pieces will come together forming one big moment. There is no beginning, middle, or end to this book making it much like the books on Tralfamadore. Was this book written so that people on earth could see what it was like to read a book in which everything happened all at once?
