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
