Nothing seems more real than time passing. We experience life as a succession of moments. But just as some of us see God as eternal, so physicists understand the truths of mathematics and the laws of nature as constant, transcending time.These laws dictate how the future will evolve: there is no freedom, no uncertainty about the future at all. Yet, argues Lee Smolin, this denial of time is holding back both physics, and our understanding of the universe. We need a major revolution in scientific thought: one that embraces the reality of time and places it at the centre of our thinking.Time, he concludes, is not an illusion: indeed, it is the best clue that we have to fundamental reality. Time Reborn explains how the true nature of time impacts on us, our world, and our universe.
