Description de l’éditeur
This is a book about the meaning of time, what it is, when it has started, how it flows and where to. It examines the consequences of Einstein's theory of relativity and offers startling suggestions about what recent research may reveal.
PUBLISHERS WEEKLY
Australian physicist and popular science writer Davies (God and the New Physics) takes readers on a mind-expanding journey as he explores the bizarre properties of Einstein's relative, flexible time; modern cosmology's assertion that time originated billions of years ago in the Big Bang; recent efforts to topple that theory; and paradoxes opened up by the prospect of time travel, which, according to Davies, is a scientific possibility. Making technical concepts accessible, Davies surveys attempts by Stephen Hawking, Murray Gell-Mann and others to reconcile Einstein's ideas with quantum physics. Among the time-bending phenomena he investigates are black holes, collapsed stars that may abolish time at their centers; kaons, subatomic particles attuned to the expansion of the universe; and antiworlds, hypothetical neighboring regions of space-time in which time flows backward. The author's speculations on causality, God and eternity make this a rewarding tour de force for nonspecialists. Illustrations.
