* 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? About Time (book) About Time: Einsteins Unfinished Revolution ( ISBN 978-2-1 ), published in 1995, 1 is the second book written by Paul Davies, regarding the subject of time.
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. Davies has worked for much of his career in astrophysics and cosmology, with emphasis on the origin and early stages of the universe, the quantum properties of black holes and the nature of time. In this book, Davies discusses why time is relative, how this relates to time travel, and then lays out a 'blueprint' for a real time machine. 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. How to Build a Time Machine by Paul Davies is a 2002 physics book that discusses the possibilities of time travel. 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.
