Product Description
Amazon.co.uk Review
The End of Time is a fascinating contribution to physics by a scholar and thinker who is taken seriously by physicists of the calibre of Wheeler and Smolin. But he has pursued a career outside the mainstream, living on a farm and refusing to get involved in traditional teaching and research. He argues that time is a purely local phenomenon, a way of seeing things, rather than something that actually meaningfully exists at the core of the universe. This consists of a vast agglomeration of Nows, single moments whose relationship with each other is intimate, but not intrinsically one of causation.
"If time is removed from the foundations of physics, we shall not all suddenly feel that the flow of time has ceased. On the contrary, new timeless principles will explain why we do feel that time flows. The pattern of the first great revolution will be repeated. Copernicus, Galileo and Kepler taught us that the Earth moves and rotates while the heavens stand still, but this did not change by one iota our direct perception that the heavens do move and that the Earth does not budge."
The many worlds hypothesis is also true and the worlds that derive from alternate possibility exist alongside each other moment by moment. Seeing things in this way solves the more recondite problems of quantum physics--Schrodinger's Cat is both dead, and alive, and never in the box in the first place and at a time before the box was thought of, and long dead all in a set of Nows that sit alongside each other in the Platonic realm which is underlying reality. There are no paradoxes because Sequence is an illusion: this is philosophical physics for those of us who like to have our brains hurt. --Roz Kaveney
Product Description
Time is an illusion. Although the laws of physics create a powerful impression that time is flowing, in fact there are only timeless 'nows'. In The End of Time, the British theoretical physicist Julian Barbour describes the coming revolution in our understanding of the world: a quantum theory of the universe that brings together Einstein's general theory of relativity - which denies the existence of a unique time - and quantum mechanics - which demands one. Barbour believes that only the most radical of ideas can resolve the conflict between these two theories: that there is, quite literally, no time at all. The End of Time is the first full-length account of the crisis in our understanding that has enveloped quantum cosmology. Unifying thinking that has never been brought together before in a book for the general reader, Barbour reveals the true architecture of the universe and demonstrates how physics is coming up sharp against the extraordinary possibility that the sense of time passing emerges from a universe that is timeless. The heart of the book is the author's lucid description of how a world of stillness can appear to be teeming with motion: in this timeless world where all possible instants coexist, complex mathematical rules of quantum mechanics bind together a special selection of these instants in a coherent order that consciousness perceives as the flow of time. Finally, in a lucid and eloquent epilogue, the author speculates on the philosophical implications of his theory: Does free will exist? Is time travel possible? How did the universe begin? Where is heaven? Does the denial of time make life meaningless? Written with exceptional clarity and elegance, this profound and original work presents a dazzlingly powerful argument that all will be able to follow, but no-one with an interest in the workings of the universe will be able to ignore.
