The Face of Chaos Victor J. Stenger Published in Free Inquiry 13, 13, Winter 1992/93. Last year the Cosmic Background Explorer (COBE) satellite made the first observation of temperature fluctuations in the cosmic microwave background. Over- enthusiastic statements on the significance of the experiment from several of the scientists interviewed prompted the media to interpret the COBE results as an unprecedented verification of the biblical view of creation. Consequently, an important scientific result was so grossly misrepresented to the public as to turn its actual meaning on its head. Some said they saw the face of God. However, physicist Simon Swordy told me saw the face of Elvis - the young Elvis. When I looked at the pictures from COBE, all I saw was the face of chaos. The COBE data added significantly to an impressive collection of prior observations that had already convinced most cosmologists that the big bang picture was basically correct. Far from demonstrating the need for a creator, the results from COBE provided support for the decade-old extension of the big-bang theory called inflation that outlines how the structure of the universe, including the laws of physics themselves, could have come about by natural means - as the universe exploded out of nothingness. The COBE observations were hardly revolutionary. Had ripples in the microwave background not been found at about the level reported, then we would have had a real scientific revolution on our hands. The sound you heard emanating from the cosmology community was a collective sigh of relief. Inflationary big-bang cosmology, the only known scheme that is consistent with the entirety of observations, had passed yet another test with flying colors. More nails were hammered into the coffins of alternative models, such as the steady- state and plasma cosmologies. According to the inflationary big-bang theory, about fifteen billion years ago our universe was confined to a region of space as small as any region of space can be: a sphere of radius 10^-33 of a centimeter, the so- called Planck length. A volume of Planck dimensions is necessarily a black hole, and the inside of a black hole is a state of maximum entropy since no information can escape. Thus, at this pregnant moment in time, the universe had no structure or design. Even if a creator, or some less personified force, had brought the universe into being prior to this moment, any record of that design would have been wiped out by quantum fluctuations and so can have had no influence on the structure of the current universe. Put simply, the inflationary big-bang theory has neither need nor room for a creator. Most people cannot imagine how the universe could have happened naturally. They presume that some transcendent force, capable of violating the laws of nature, was required to bring the material world into existence. The common, intuitive arguments are basically twofold, and I will express them as follows: (1)The no free lunch argument: "You can't get something for nothing." (2)The argument from design: "How could all of this (gesturing to the world around us) have happened by chance?" These two familiar expressions of a perceived need for a miracle to create an orderly universe can be directly translated into the more precise language of physics. In fact, they represent vernacular statements pertaining to the seeming violation, at the beginning of the universe, of two of the most fundamental laws of physics. The no free lunch argument claims a violation of the first law of thermodynamics in producing the universe. The argument from design asserts that the second law of thermodynamics must also have been broken at the beginning of time. Despite this intuition, the fact that organized matter and energy are now distributed throughout billions of light-years of space does not imply a violation of either the first or second law of thermodynamics. The inflationary model, together with Einstein's general relativity, show how a quantum fluctuation at the Planck time, allowed by the uncertainty principle of quantum mechanics and violating no principle of physics, would take only 10^-42 of a second to grow to a sphere the size of a proton containing a vacuum energy equivalent to all the visible mass in the current universe. Likewise, the organization of matter into galaxies and planets does not require a violation of the second law of thermodynamics - now or in the past. Though the universe starts as a black hole of maximum entropy, or maximum disorder, it explodes into an expanding relativistic gas having less than its maximum allowable entropy. Thus the microwave background is easily able to absorb the entropy from any localized structure, like a galaxy or a planet, that spontaneously forms - induced by random statistical fluctuations of the type observed by COBE. Far from providing the evidence for a creator sought by believers, any observations that support the inflationary big-bang theory, such as the data from COBE, make the existence of a creator that much more unlikely. The currently existing structure of the universe, including the laws of physics, could very well have been spontaneously generated after the Planck time, by the natural processes of self-organization and perhaps even a kind of Darwinian natural selection from among a random sample of all possibilities. Those who look to science to bolster their faith in the fantasies of a creator and an invisible world of the spirit won't find such support in the ripples of the big bang or any other scientific observation. ___________________________________ These ideas are discussed in the author's books: Not By Design: The Origin of the Universe, (Prometheus Books,1988), Physics and Psychics: The Search for a World Beyond the Senses (Prometheus Books,1990) and in his article "The Universe: The Ultimate Free Lunch," European Journal of Physics 11 (1990), p. 236.
