"Bucky Fuller thought big," Wired magazine recently noted, "Arthur C. Clarke thinks big, but Cliff Pickover outdoes them both." And now, in his newest book, Cliff Pickover outdoes even himself, probing a mystery that has baffled mystics, philosophers, and scientists throughout history--Whatis the nature of time? In Time: A Traveler's Guide, Pickover takes readers to the forefront of science as he illuminates the most mysterious phenomenon in the universe--time itself. Is time travel possible? Is time real? Does it flow in one direction only? Does it have a beginning and an end? What is eternity? Theseare questions that Pickover tackles in this stimulating blend of Chopin, philosophy, Einstein, and modern physics, spiced with diverting side-trips to such topics as the history of clocks, the nature of free will, and the reason gold glitters. Pickover includes numerous diagrams so readers have notrouble following along, computer code that lets us write simulations for various aspects of time travel, and an on-going science fiction tale featuring quirky characters who yearn to travel back in time to hear Chopin play in person. By the time we finish this book, we understand such seeminglyarcane concepts as space-time diagrams, light cones, cosmic moment lines, transcendent infinite speeds, Lorentz transformations, superluminal and ultraluminal motions, ninkowskian space-times, Godel universes, closed timelike curves, and Tipler cylinders. And most important, we will understand that time travel need not be confined to myth, science fiction, Hollywood fantasies, or scientific speculation. Time travel, we will realize, is possible.
