One of our foremost thinkers and public intellectuals offers a radical new view of the nature of time and the cosmos. The fact that time is real may seem obvious. You experience it passing every day when you watch clocks tick, bread toast, and children grow. But most physicists see things differently, from Newton to Einstein to today�s quantum theorists. For them, time isn�t real. You may think you experience time passing, but they say it�s just an illusion. Lee Smolin, author of the controversial bestseller The Trouble with Physics, argues this limited notion of time is holding physics back. It�s time for a major revolution in scientific thought. The reality of time could be the key to the next big breakthrough in theoretical physics. What if the laws of physics themselves were not timeless? What if they could evolve? Time Reborn offers a radical new approach to cosmology that embraces the reality of time and opens up a whole new universe of possibilties. There are few ideas that, like our notion of time, shape our thinking about literally everything, with major implications for physics and beyond�from climate change to the economic crisis. Smolin explains in lively and lucid prose how the true nature of time impacts our world.
