The last thirty years have witnessed a major revival in the philosophical, theological, scientific, and popular literature of the traditional design argument for theism. Probably the most convincing and widely discussed of these arguments is based on the so-called "fine-tuning" of the cosmos, which refers the fact that the parameters of physics and the initial conditions of the universe are balanced on a razor's edge for life to occur. For example, calculations by Brandon Carter indicate that if the force of gravity had been stronger or weaker by one part in 1040, then life-sustaining stars could not exist (Davies, 1984, p. 242); similarly, calculations indicate that if the strong nuclear force, the force that binds protons and neutrons together in an atom, had been stronger or weaker by as little as 5%, life would be impossible. ( Barrow and Tipler, p. 322.) As the eminent Princeton physicist Freeman Dyson notes, "There are many . . . lucky accidents in physics. Without such accidents, water could not exist as liquid, chains of carbon atoms could not form complex organic molecules, and hydrogen atoms could not form breakable bridges between molecules" (1979, p. 251)--in short, life as we know it would be impossible.
