Cosmic Clowning: Stephen Hawking's "new" theory of everything is the same old CRAP

By John Horgan

Maybe it's the perpetual Mick Jagger smirk, which implies that to him everything, including his own physical plight, is a joke. But I've always thought of Stephen Hawking—whose new book The Grand Design (Bantam 2010), co-written with Leonard Mlodinow, has become an instant bestseller—less as a scientist than as a cosmic, comic performance artist, who loves goofing on his fellow physicists and the rest of us.

This penchant was already apparent in 1980, when the University of Cambridge named Hawking Lucasian Professor of Mathematics at Cambridge, the chair held three centuries earlier by Isaac Newton. Many would have been cowed into caution by such an honor. But in his inaugural lecture, "Is the End in Sight for Theoretical Physics?", Hawking predicted that physics was on the verge of a unified theory so potent and complete that it would bring the field to a close. The theory would not only unite relativity and quantum mechanics into one tidy package and "describe all possible observations." It would also tell us why the big bang banged and spawned our weird world rather than something entirely different.

At the end of his speech Hawking slyly suggested that, given the "rapid rate of development" of computers, they might soon become so smart that they "take over altogether" in physics. "So maybe the end is in sight for theoretical physicists," he said, "if not for theoretical physics." This line was clearly intended as a poke in his colleagues' ribs. Wouldn't it be ironic if our mindless machines usurped our place as discoverers of Cosmic Truth? Hilarious!

The famous last line of Hawking's monumental bestseller 
A Brief History of Time (Bantam 1988) was also a joke, although many people didn't get it at the time. A final theory of physics, Hawking declared, "would be the ultimate triumph of human reason—for then we should know the mind of God." Hawking seemed to imply that physics was going to come full circle back to its spiritual roots, yielding a mystical revelation that tells us not just what the universe is but why it is. Science and religion are compatible after all! Yay!

But Hawking ain't one of these New Agey, feel-good physicist–deists like John Barrow, Paul Davies, Freeman Dyson or other winners of the
 Templeton Prize for Progress Toward Research or Discoveries about Spiritual Realities. Deep inside Brief History Hawking showed his true colors when he discussed the no-boundary proposal, which holds that the entire history of the universe, all of space and time, forms a kind of four-dimensional sphere. The proposal implies that speculation about the beginning or end of the universe is as meaningless as talking about the beginning or end of a sphere.

In the same way a unified theory of physics might be so seamless, perfect and complete that it even explains itself. "What place, then, for a creator?" Hawking asked. There is no place, he replied. Or rather, a final theory would eliminate the need for a God, a creator, a designer. Hawking's first wife, a devout Christian, knew what he was up to. After she and Hawking divorced in the early 1990s she revealed that one of the reasons was his scorn for religion.

Hawking's atheism is front and center in 
Grand Design. In an excerpt Hawking and Mlodinow declare, "There is a sound scientific explanation for the making of our world—no Gods required." But Hawking is, must be, kidding once again. The "sound scientific explanation" is M-theory, which Hawking calls (in a blurb for Amazon) "the only viable candidate for a complete 'theory of everything'."

NOTA DESTE BLOGGER:


No blog Quiprona lemos:


"Muita gente ficou nervosa com o lançamento do livro “The Grand Design”, por Stephen Hawking e Leonard Mlodinow. Isso porque o físico de Cambridge e seu colega lançam mão da ideia de que Deus não seria necessário para que o Big Bang tivesse ocorrido, levando-se em conta que as melhores explicações para a formação do universo devem incluir, necessariamente, a lei da gravidade."

O artigo de John Horgan acima mostra que não é somente isso que deixou as pessoas nervosas com o lançamento deste livro: é também a teoria proposta de multiversos que está mais para metafísica do que ciência verdadeira.
