Riassunto

What is time? The Janus Point offers a ground-breaking solution to one of the greatest mysteries in physics.

For over a century, the greatest minds have sought to understand why time seems to flow in one direction, ever forward. In The Janus Point, Julian Barbour offers a radically new answer: it doesn't.

At the heart of this book, Barbour provides a new vision of the Big Bang - the Janus Point - from which time flows in two directions, its currents driven by the expansion of the universe and the growth of order in the galaxies, planets and life itself. What emerges is not just a revolutionary new theory of time, but a hopeful argument about the destiny of our universe.

'Both a work of literature and a masterpiece of scientific thought' Lee Smolin, author of The Trouble with Physics

'Profound...original...accessible to anyone who has pondered the mysteries of space and time' Martin Rees, Astronomer Royal

'Takes on fundamental questions, offering a new perspective on how the Universe started and where it may be headed' Science Magazine

The Janus Point is his first book in twenty years and the culmination of five decades' work.

Dalla quarta di copertina

Time is perhaps the greatest mystery in physics. Despite the fact that the fundamental laws of physics don't distinguish between past and future, we do. And so, for over a century, the greatest minds have sought to understand why time seems to flow in one direction, ever forward. In The Janus Point, Julian Barbour, author of the classic The End of Time, offers a radically new answer: it doesn't.

Most physicists believe that the second law of thermodynamics, and the increase of disorder that it describes, forces an irreversible, unidirectional flow of time. Barbour shows why that argument fails and demonstrates instead that our universe isn't heading for disorder; rather, it emerged from it. At the heart of his argument is a new vision of the Big Bang that Barbour calls the Janus Point, from which time flows in two directions, its currents driven by the expansion of the universe and the growth of order in the galaxies, planets, and life itself.

Monumental in vision and scope, The Janus Point is not just a new theory of time: it's a hopeful argument about the destiny of our universe. While most physicists predict that the universe will become mired in disorder, Barbour sees the possibility that order - the stuff of life - can grow without bound.
