The main concerns of the book are to explain the role played by time in the keystones of modern physics, general relativity and quantum mechanics. Originally published on my blog here in January 2000.Ībout Time is an eminently readable popular account of the current ideas about time in physics, with a short historical section examining philosophical perceptions of time from the ancient Greeks to the time of Newton. * Is it possible to travel backward - or forward - in time?Ībout Time weaves physics and metaphysics in a provocative contemplation of time and the universe. * Is the passage of time merely an illusion? * Does the universe have a beginning and an end?
Davies explores unanswered questions such as: In About Time, Paul Davies discusses the big bang theory, chaos theory, and the recent discovery that the universe appears to be younger than some of the objects in it, concluding that Einstein's theory provides only an incomplete understanding of the nature of time. The eternal questions of science and religion were profoundly recast by Einstein's theory of relativity and its implications that time can be warped by motion and gravitation, and that it cannot be meaningfully divided into past, present, and future. An elegant, witty, and engaging exploration of the riddle of time, which examines the consequences of Einstein's theory of relativity and offers startling suggestions about what recent research may reveal.
