The End of Time: The Next Revolution in PhysicsRichard Feynman once quipped that "Time is what happens when nothing else does." But Julian Barbour disagrees: if nothing happened, if nothing changed, then time would stop. For time is nothing but change. It is change that we perceive occurring all around us, not time. Put simply, time does not exist.In this highly provocative volume, Barbour presents the basic evidence for a timeless universe, and shows why we still experience the world as intensely temporal. It is a book that strikes at the heart of modern physics. It casts doubt on Einstein's greatest contribution, the spacetime continuum, but also points to the solution of one of the great paradoxes of modern science, the chasm between classical and quantum physics. Indeed, Barbour argues that the holy grail of physiciststhe unification of Einstein's general relativity with quantum mechanicsmay well spell the end of time.Barbour writes with remarkable clarity as he ranges from the ancient philosophers Heraclitus and Parmenides, through the giants of science Galileo, Newton, and Einstein, to the work of the contemporary physicists John Wheeler, Roger Penrose, and Steven Hawking. Along the way he treats us to enticing glimpses of some of the mysteries of the universe, and presents intriguing ideas about multiple worlds, time travel, immortality, and, above all, the illusion of motion.The End of Time is a vibrantly written and revolutionary book. It turns our understanding of reality insideout.

User Review  timanda  LibraryThingIn this wonderful book, Barbour (a physicist) attempts to explain what time is. The book isn't aimed at (or likely to be fun for) the general audience. It's aimed at people who took at least a little ... Read full review

User Review  Jewsbury  LibraryThingBarbour has thought long and hard about how to abolish time as a fundamental quantity. He is inspired by what he presumes to be a Machian requirement – a cosmos of 3space defined only by relative ... Read full review
