Twenty years after Stephen Hawking's 9-million-copy selling A Brief History of Time, pioneering theoretical physicist Sean Carroll takes our investigation into the nature of time to the next level. You can't unscramble an egg and you can't remember the future. But what if time doesn't (or didn't!) always go in the same direction? Carroll's paradigm-shifting research suggests that other universes experience time running in the opposite direction to our own. Exploring subjects from entropy and quantum mechanics to time travel and the meaning of life, Carroll presents a dazzling new view of how we came to exist.

No one is better equipped to take readers on a rollercoaster ride through time, space, and the origins of the universe than Caltech theoretical physicist Carroll, cofounder of Cosmic Variance, one of the top science blog sites. "We're not thinking small here," Carroll announces with glee before launching into his topic. Time is a medium we move through and a way to sequence events. But the "Arrow of Time' is also the only feature of the universe with one irreversible direction: time goes forward. This fact plays an important role in the second law of thermodynamics: the entropy (disorderliness) of an isolated system either remains constant or increases with time. This has implications for our understanding of the "Big Bang" origins of the universe. We may not be able to travel back in time, but we can find ways to peer back across it and see clues to how the universe evolved, thanks to such discoveries as quantum mechanics and relativity theory. Carroll writes with verve and infectious enthusiasm, reminding readers that "science is a journey in which getting there is, without question, much of the fun." Illus.
