Which brings us on to the second revolutionary idea of the book which is to link the cosmos – and the physical laws under which it operates – to Darwinian natural selection.

Cosmological natural selection (fecund universes)

Some of these have to do with the elementary particles themselves: Those with a strong interest in philosophy and some interest in science or cosmology. You tell it the dimension of spacetime, and something about how the world should look. As he argues for this new view, Smolin introduces the reader to recent developments in a wide range of fields, from string theory and quantum gravity to evolutionary theory the structure of galaxies. Kee, a unique theory is unlikely to yield the parameters of our Universe so the chances that it exists is 1 in 10 The revelation of the existence of other galaxies naturally leads to the question “Are there also other universes?

T he physical world is governed by forces. At the same time, it is unlikely that there lifee any lifs in high school or university that is more disliked than physics. The fossil record tells us that the biosphere has become more organized and more varied over time.

There are several reasons for this, one of which is certainly the great difficulty and xmolin of making new experiments that probe layers of structure smaller than those described by the standard model. If we were interested only in feeling better about ourselves, we might be happy to jump from vitalism to a kind of pantheism according to which life exists because the universe is itself alive.

I’m looking forward to reading his other books! The Moment of Complexity: In such a hypothetical world, there might be complex self-organizing units smolun mimic what we call life.

And how is it that our place, Earth, stays in a perpetual state that denies the law of entropy such that it can support life? If true, it represents a great simplification in our understanding of the world and a great triumph of theoretical physics. Many scieentists would simply “throw their hands up” saying the world is simply the way it is. Cosmological natural selection CNSalso known as fecund universesis a prominent theory of universe evolution, development and lew originally proposed by eminent theoretical physicist and quantum gravity scholar Lee Smolin in To put it smolim way, one of the questions we will be seeking to answer in the following chapters is whether it is purely an accident, or whether it is to some extent necessary, that this, or any, cosmos is a universe of light and life.

Cosmologist Edward Harrisonin what was apparently the first CNS-I hypothesis to be published in a peer-reviewed journal, independently proposed that the purpose of intelligent life is to produce successor universes, in a process driven by natural selection at the universal scale. But when cosmis raise our eyes from the molecules, and look at the universe on a large scale, we also see a hierarchical structure.

And I’ve fallen in love with galaxies The revolution began in earnest when Kepler abolished the crystal spheres and cast the planets adrift in empty space. It is exactly such a new look that I would like to propose we take to the problems of elementary particle physics.

May 17, Krischelle marked it as to-read. Vidal proposes that an intervention of intelligence in the universal reproduction process should be named “Cosmological Artificial Selection” CAS. This question has a simple answer: I’ve put it down, for now. Gravitation propels our Earth around the Sun and causes the Universe to expand. Who should read this book? Meanwhile in the scientific literature, Louis Crane’s Meduso-anthropic principle proposed, in an arxiv.

However, the real difference between Cosmological Natural Selection and Anthropic reasoning is that the former gives a mechanism to explain the relationship between possible configurations of the constants of nature, llfe the later does not. Each of us is a living thing.

Hence, we may need a paradigm shift in physics, something which is quite taboo among physicists. It is often stressed that carbon is required because it is the only element that forms a sufficient variety of stable molecular structures.

Henry Tye, a string theorist from Cornell University, had told me of his computer program to produce new string theories. The rate of expansion of the Universe, the collapsing processes that build stars, stellar evolutions and supernova production would all change. The general idea is thought-provoking. I have to admit that I AM a physicist and I am obviously biased because topics in this book are exactly what I find most interesting, but I have to say that I’m surprised at how much I actually learned from a book without a single equation.

We know that this is not the case. When we combine CNS with dark energy models, rather than an oscillating universe which returns all its evolutionary species to a single replication point, our universe appears to be generating a diverse set of continually branching replications, just as we observe in any evolutionary developmental history of living systems exploring a phenospace.

That takes real s One of the most illuminating books on theoretical physics I’ve ever read.

He further develops this speculative idea in his transcension hypothesisciting apparent advantages of black hole-like conditions for the perpetuation of life and intelligence in dmolin entropic universe. Another, related meaning of entropy is that it is a measure of disorganization. The Life of the Cosmos is well written in a highly intellectual style.

Seen from the largest scales, the galaxies are the basic structural units of the organization of the universe. A philosophy that tells us to explain things by breaking them into parts will not help us when we confront the question of understanding the things that have no parts. Nevertheless, many such models do allow for a multitude of gravitationally-driven “Small Crunches” in an accelerating universe.

Someone might even dare smllin say “Why God? At the same time, the laws of Nature and the values of mass quantities in the new “daughter universes” differ slightly from those of the “mother universe. There’s plenty more to say about this book and I might do so later, but that’s good for now.

Lots of brilliant people I know recommend it highly. Anyone who sets out to teach ideas from physics to those who are not specialists, whether as a teacher in a lecture room or through a book such as this one, faces a curiously paradoxical situation.
