Ask physicists what time actually is, and the answer might shock you: They have no idea. Even more
surprising, the deep sense we have of time passing from present to past may be nothing more than an
illusion. How can our understanding of something so familiar be so wrong? In search of answers, Brian
Greene takes us on the ultimate time traveling adventure, making the case that the past, present, and
future all exist at once. This journey brings us all the way back to the Big Bang, where physicists think the
ultimate secrets of time may be hidden. You’ll never look at your wristwatch the same way again.
