Stephen Hawking's Junk Science Atheism

MEXICO CITY, September 6, 2010 ( - World-famous physics professor Stephen Hawking is making waves and headlines by claiming in his new book, The Grand Design, that God is not necessary to explain the existence of the universe because, in his words, "as recent advances in cosmology suggest, the laws of gravity and quantum theory allow universes to appear spontaneously from nothing."

"Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist," he adds. "It is not necessary to invoke God to light the blue touch paper and set the universe going."

Although the book is not yet available to the public and only a few paragraphs have been quoted in the commercial media, it appears that Hawking is playing the same game he played in his celebrated work, A Brief History of Time, which established his fame in the 1980s and has sold millions of copies worldwide. He takes theories that he admits are unproven, then uses verbal sleight of hand to begin treating them subtly as fact. Even worse, however, is his method of spinning ludicrous philosophical conclusions from such theories, implying that they simply follow from the science.

Hawking makes hay out of the theory of the "vacuum fluctuation" to imply that matter can simply spontaneously appear, created out of "nothing." A vacuum fluctuation is an event in which the forces of nature manifest themselves briefly as "virtual particles," so briefly they cannot be directly observed, and then disappear. Such theoretical entities seem to be well supported by experimental evidence. However, physics has not abandoned the principle of the conservation of mass and energy, and the "nothing" that such particles receive their mass from is in fact something very real, known as "vacuum energy," which permeates all of space.

"Quantum cosmologists," such as Hawking, have made a cottage industry out of speculating that events like vacuum fluctuations could result in the creation of entirely new worlds, although they have no direct experimental proof of such events occurring. This is in keeping with Hawking's general obsession with highly theoretical constructs that have little hard data to support them. He has, for example, spent many years theorizing on the properties of black holes, entities whose very existence remains unproven. This is why, despite his great fame and unquestioned ability, he has never received the Nobel Prize in physics.

In his latest bid for publicity, Hawking appears to be employing his usual shell-game verbiage to imply the "spontaneous" appearance of the physical world, with Nothing itself as a creator. His theory emphasizes vacuum fluctuations, but it apparently slips his mind that the law of conservation of energy remains an axiom of physics. He defines "nothing" in a very peculiar way -- apparently the energy of the vacuum is "nothing." Moreover, Hawking cites two particular "nothings" to justify his something-from-nothing theory, which are the laws of gravity and quantum mechanics (the laws governing microphysical particles). He says that these laws make such events possible. Are gravity and quantum-physical laws "nothing"?

Hawking's current statements are similar to those he made in his Brief History of Time, where he tried to imply that the universe came out of nothing because research suggests that the positive and negative energy of the universe balance each other out. Gravity, which is an attractive force, is understood as "negative energy," and the expansive movement of the universe is seen as "positive energy."

Of course, if you add together a negative number and positive number whose absolute values are equal, you get zero, but so what? Are we to conclude that because these two variables sum to nothing, that they had their origin in nothing, or perhaps that they don't even exist because they cancel each other out? If so, how could one place them as terms in the equation in the first place? Hawking never bothers to answer basic questions like that, apparently hoping that his naive and sympathetic audience won't ask them.
