If you want to know why atheists seem to have given up the scientific card, the current issue of Discover magazine provides part of the answer. The magazine has an interesting story by Tim Folger which is titled “Science’s Alternative to an Intelligent Creator.” The article begins by noting “an extraordinary fact about the universe: its basic properties are uncannily suited for life.” As physicist Andrei Linde puts it, “We have a lot of really, really strange coincidences, and all of these coincidences are such that they make life possible.”
Too many “coincidences,” however, imply a plot. Folger’s article shows that if the numerical values of the universe, from the speed of light to the strength of gravity, were even slightly different, there would be no universe and no life. Recently scientists have discovered that most of the matter and energy in the universe is made up of so-called “dark” matter and “dark” energy. It turns out that the quantity of dark energy seems precisely calibrated to make possible not only our universe but observers like us who can comprehend that universe.
Even Steven Weinberg, the Nobel laureate in physics and an outspoken atheist, remarks that “this is fine-tuning that seems to be extreme, far beyond what you could imagine just having to accept as a mere accident.” And physicist Freeman Dyson draws the appropriate conclusion from the scientific evidence to date: “The universe in some sense knew we were coming.” ...
