Product Description
Amazon.co.uk Review
Science fans, hold on to your hats! Lee Smolin, a professor at the Center for Gravitational Physics and Geometry at Pennsylvania State University, is about to take you on the ride of your life. Imagine, if you will, the theory of evolution applied to physics. What if our universe is so ideally adapted to life because it developed that way? What if ours is just one among many thousands of universes, all engaged in a cosmic survival-of-the-fittest struggle? These are just two of the wildly original theories Smolin posits in The Life of the Cosmos, in which Alice in Wonderland meets quantum physics. According to Smolin, the majority of today's physicists still regard physical laws as immutable, mathematical and eternally true--to them, the universe is an intricate mechanism, a cosmic clock. But what if the laws of physics aren't really "laws" at all, but rather an evolving, developing process of natural selection that began even before the Big Bang?
From Smolin's initial theory, it's a short step to black holes, alternate universes, string theory, gauge symmetry and knots--all complicated abstractions that Smolin describes and explains in a remarkably comprehensible way. Even if you don't agree with Smolin's science, his book makes for great mind-bending reading and more than a little food for thought. If nothing else, The Life of the Cosmos proves once and for all that there really is intelligent life on this planet.
Review
The most exciting and possibly the most important science book of 1997. Smolin is an American cosmologist, who argues that the universe is literally alive, and that it has evolved from mutations affecting successive generations of universes. This is not a crank theory, but a fully worked out scientific hypothesis, which weaves together Einstein's theory of relativity and natural selection, presenting the synthesis in an absorbing style. (Kirkus UK)
Physics has long assumed that the laws of nature are immutable; here's a cosmological theory that challenges even that common-sense notion. The great problem facing physics at the end of the 20th century remains the integration of relativity and quantum theory. While both have scored impressive triumphs in their spheres of concern, the two operate at different poles of the physical universe: Relativity concerns itself with large objects and great distances, whereas quantum theory is at home with subatomic particles. And while quantum theory has brilliantly accounted for three of the four major forces in the universe, it has failed to make heads or tails of gravity - the one force that affects all the particles in the universe, no matter what the distance between them. A further difficulty, from Smolin's point of view, is that the ratios of the masses of the known particles do not fall into any coherent pattern, and small changes in those parameters would lead to a universe radically different from ours. So why is our universe as we see it? Why, for that matter, do we exist at all? Smolin (Physics/Penn. State Univ.) suggests that an evolutionary principle has been at work, that the Big Bang was only the most recent in a series of creations, and that the laws of physics can vary (although only a tiny bit) with each new bang. Universes that tend to create many stars (and thus many black holes, as those stars die) can give birth to more descendants than those with a paucity of stars. Thus the universe evolves according to a principle similar to natural selection. Much of the material is fascinating, and Smolin gives the reader a thorough tour of the latest in cosmological speculation. The early chapters are slow going, but once his argument builds up momentum, Smolin is a thought-provoking theorist. (Kirkus Reviews)
