This is the theory of cosmological natural selection. It also discusses what gravity, space time, and time would be like at a quantum level, and why there are so many inconsistencies in physics and in reality itself.
That life arose from a simpler world seems the ultimate miracle. But even more than this, during their period of exile from the mainstream, the string theorists realized that their theory naturally gave rise to an interaction that had all of the hallmarks of the gravitational force. The answer to this question is the same as the answer to the other questions we raised in this chapter: As the theory goes, formation of new black holes in a universe give rise to child universes, etc.
Once I got the hang of the idea, I was ready to be done with the book as Smolin repeatedly beats dead horses and reiterates his points. One reason to question radical atomism is that it must eventually lead either to infinite regress or to a brick wall. Why doesn’t the neutrino have any electric charge? The configuration in which all parts of a system have the same temperature, density and chemical composition is called thermodynamic equilibrium. Paleontologists have mapped out a sketchy, but impressive, three-billion-year-long picture of how the human has arisen, starting from a microbe, evolving to a worm, growing into a fish, emerging as a tetrapod on land, and changing into a mammal, then a monkey, then a man.
For example, here are some sentences from a typical paragraph: Imagine that we have stepped for the first time, not into a universe, but into a library.
Taking an adaptationist view of CNS, in an approach called CNS-I CNS with intelligence Price argues that intelligence is more likely than black holes to be an adaptation self-designed by natural selection.
The Ecology of the Galaxy. All but the lightest elements were forged in stars.
Cosmological natural selection (fecund universes)
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. Thus, string theory had the potential to unify all of physics in a simple framework, in which all phenomena arise from the motion and vibrations of fundamental one-dimensional strings.
Lee Smolin is a theoretical physicist who has made influential contributions to the search for a unification of physics. We humans must live in one of these special universes. 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 itself is alive.
Comparison between galaxies and living things is fascinating. Physicists can compute the trajectory of a missile using Newton’s laws of motion or the rate at which a nucleus disintegrates. The dependence of life on light underlies so many metaphors and so much of the imagery of our culture think of the fear of the dark that to even quote examples is to risk cliche, but let me mention one, that to understand something is to attain an insight.
These ideas may seem astonishing to the reader, but theorists have often contemplated them. It’s a nice way of dropping things into differently labeled buckets, but I fail to see how it ties in with the thesis of the book.
Instead, to understand a quark or an electron, we may have to know something about the history or organization of the universe. I have been teaching physics to non-science students for much of my career.
Some of these reasons come from the logic of atomism itself. Mysticism Like the word “god”, this is another red flag; and it appears 25 times In order to get the force to come out with the right strength, all they had to do was fix the length of the string to be about the Planck length. They are like that because they always were and always will be.
Molecules can be organized many different ways, as solids, crystals, liquids, gases, just as there are many kinds of texts. Feb 04, James Cosmoa rated it really liked it Shelves: Who should read this book? Smolin is good at acknowledging criticism of the theory and does his best to defend it. The reader must have a high IQ — deep philosophical reasoning and non-trivial logical analyses are involved.
The fossil record tells us that the biosphere has become more organized and more varied over time.
og The Cosmology of an Interesting Universe. Smolin writes in complex sentences, compounded lite a generous sprinkling of grammatical errors, all of which conspire to make it a hard, slow, tedious read.
We also don’t understand why quantum theory is true and what it describes. Who has not looked up at the stars, or gazed at a tree or a kitten and wondered what the universe is and what our place in it might be? So it is possible that many universes exist and that Nature’s parameters change, although both ideas are conjecture.
Although the consistent quantum theory thr gravity is not yet known, some cosmologists believe that somlin multi-universe picture of the world will emerge as part of quantum gravity. Still, there is no denying the attraction such a view holds for many people. FYI the other is “The Selfish Gene” First of all, Smolin has some crazy-sounding things to say, but he uses tight, scientific arguments, and he’s the real deal, a professor at a Canadian University with a team of researchers working under him.
The atoms are organized into an enormous number of different molecules, just as the letters spell out an enormous number of words. This contrasts with Smolin’s view that black holes are the central adaptation, and intelligent life a byproduct of selection. For like 10 pages!
The Life of the Cosmos
One may try to question whether our Universe really is improbable. Beyond the Anthropic Principle. Branching universe ensembles may be lf way to maximize diversity, resilience, and adaptiveness, over an alternative “all eggs in one basket” Big Crunch.
