Chi ama i libri sceglie Kobo e inMondadori. download the eBook Price: The spare and earnest voice that Mr. Hawking employed with such appeal in A Brief History of Time has been replaced here by one that is alternately condescending, as if he were Mr. Rogers explaining rain clouds to toddlers, and impenetrable.
But that doesn't stop the authors from asserting that it explains the mysteries of existence In the absence of theory, though, this is nothing more than a hunch doomed — until we start watching universes come into being — to remain untested.
The lesson isn't that we face a dilemma between God and the multiverse , but that we shouldn't go off the rails at the first sign of coincidences. Cosmologists embrace these features by envisaging sweeping "meta-laws" that pervade the multiverse and spawn specific bylaws on a universe-by-universe basis.
The meta-laws themselves remain unexplained — eternal, immutable transcendent entities that just happen to exist and must simply be accepted as given. In that respect the meta-laws have a similar status to an unexplained transcendent god.
But when it comes to the laws that explain the big bang, we are in murkier waters. Marcelo Gleiser , in his article "Hawking And God: An Intimate Relationship", stated that "contemplating a final theory is inconsistent with the very essence of physics, an empirical science based on the gradual collection of data.
In fact, I find it quite pretentious to imagine that we humans can achieve such a thing.
Maybe Hawking should leave God alone. The book's rather conventional claim that "God is unnecessary" for explaining physics and early universe cosmology has provided a lot of publicity for the book. Critics call this the " Alice's Restaurant problem," a reference to the refrain of the old Arlo Guthrie folk song: "You can get anything you want at Alice's Restaurant.
The anthropic principle has always struck me as so dumb that I can't understand why anyone takes it seriously. It's cosmology's version of creationism. The physicist Tony Rothman , with whom I worked at Scientific American in the s, liked to say that the anthropic principle in any form is completely ridiculous and hence should be called CRAP. Hawking attempts to explain sophisticated and complex mathematical ideas in an unsophisticated, perhaps childlike but charming way.
He briefly covers the history of ideas about the universe from Aristotle, Augustine, Newton, Einstein, Hubble, and Feynman. He then explains the Big Bang, black holes, and space-time and incorporates these thoughts into the search for a unified theory of everything. Although Hawking does not announce the arrival of the Theory of Everything, he does explain, in simple metaphors, the flavor of what such a theory would encompass.
One of the more important concepts of his involves the idea that the "beginning" of the universe does not necessarily imply a singularity or in holistic terms, a oneness. If we wish to hold consistency with quantum mechanics the most successful scientific theory to date then a no-boundary condition would best describe the beginning.
Needless to say, this contradicts many religious ideas about a creation although he empathizes that these ideas represent only a proposal. Hawking represents one of the most brilliant theoretical scientists of our time.
He advocates the idea of communicating the ideas theoretical science in a way to make it understandable, in principle, to everyone, not just scientists. Hawking has an acute awareness of the religious impact of his theoretical studies and explains in a clear but inoffensive way that the universe does not conform to the common belief of an all powerful Creator.
A few quotes from the book: An expanding universe does not preclude a creator, but it does place limits on when He might have carried out his job. We now know that our galaxy is only one of some hundred thousand million that can be seen using modern telescopes, each galaxy itself containing some hundred thousand million stars. This behavior of the universe [expanding universe] could have been predicted from Newton's theory of gravity at any time in the nineteenth, the eighteenth, or even the late seventeenth centuries.
Yet so strong was the belief in a static universe that it persisted into the early twentieth century.
