Written in clear language that makes the cutting-edge science of quarks, neutrinos, wormholes, and metaverses accessible to the layman, "The Last Three Minutes" treats readers to a wide range of conjectures about the ultimate fate of the universe. Along the way, it takes the occasional divergent path to discuss some slightly less cataclysmic topics such as galactic colonization, what would happen if the Earth were struck by the comet Swift-Tuttle (a distinct possibility), the effects of falling in a black hole, and how to create a " baby universe." Wonderfully morbid to the core, this is one of the most original science books to come along in years."It is always a pleasure to read this kind of meditation when it is carried out by a thinker of the breadth and awareness of Paul Davies." "--New York Times"
"Davies guides the reader on an imaginary journey into deep time, as the celestial clockwork winds out to infinity, bearing our descendants with it."--Laurence A. Marschall, "The Sciences"
"Davies has written a highly readable book that makes a commendable companion to "The First Three Minutes."--Elizabeth Maggio, "Washington Post"

A truly wonderful book - in its literal sense, discussing the fate of the sun (OK, done before but not as poetically as this) and the ultimate nightfall - "the era of light will be over forever", and the alarming violence of the crunch scenario - "The Universe now has an elegant but sinister simplicity. It has but seconds to live.." Concepts discussed elsewhere many times but NEVER EVER EVER made as spine-tingling as this.
Come on, more people should read this book. Just read it, please, you'll love it.
It was not surprising to me to see his name on the Science Masters Series. The series has basic introductions to many of the key issues in science today -- evolution, origins of life, cognitive science, time, computer science, and more. Each volume is relatively short -- 'The Last Three Minutes' has a mere 150 pages of text that is not too dense, sparing technically and mathematically without losing much conceptually.
The issue of the end of the universe is one of the 'hot spots' of astrophysics and cosmology, and so there are elements of this book that are already a bit out of date, despite being less than a decade old. However, given the speculative nature of many 'discoveries' in this field, it is impossible to say if anything is truly out of date or false at the present time.
Davies explores the end of the universe by setting the stage -- drawing from current thinking about the origins of the universe, in fact one of the options for conjecture, in a closed universe system, would be that the last three minutes would resemble quite closely the first three minutes. Davies looks at the various processes -- stellar evolution and decay, gravitational issues, overall radiation depletion, energy-fuel consumption -- and draws these together for the various theories about the end of the universe.
Davies shows the ideas of the closed/collapsing universe (a view not widely held today) and of the infinitely expanding universe (the current reigning theory), giving ideas about the variables required to tip the scales in one direction or the other. Even with an infinitely expanding universe, however, all is not necessarily well with the world -- the universe runs the risk (in the future so distant there is no realistic way of expressing it in terms of time we know) of becoming a dark, deep freeze with no activity left, and all matter becoming inert and inactive in every respect.
Davies speculates on what this means for the survival of humanity and human history -- how can information be preserved? How can our species go on in the face of this? Such speculation is pure conjecture; the time distances are so far removed that nothing we devise will likely come close to resembling an actual answer to this. However, it is interesting as a mental exercise, and leads the reader hopefully to further reading.

I believe that the author is also too optimistic about the fate of mankind in the universe after the dying of the sun. If mankind doesn't commit suicide, he predicts not less than a colonization of the entire Milky Way.
As always with Paul Davies, the different stories are told in a clear and easily comprehensible vocabulary. This book is written in a swinging style and is as fascinating as a dazzling thriller.
A very interesting and stimulative read.
