That’s what my brother Tim calls it. He isn’t a scientist, just a bright layman interested in science. He is especially interested in scientific anomalies and the water window is one of them. It is such a striking exception to normal laws of science that it convinced him, a skeptic, of the fact of intelligent design.
Yet he can’t seem to find any scientists or other bright laymen who see its significance. He’s excited about it and he very much wants to find someone out there to be excited with him.
If the rules of chemistry were predictable (consistent), water on this planet would boil at -132 degrees and freeze at -148 degrees. There would be no liquid water on earth, just steam. Carbon-based life forms like us would not be possible.
The attached page from a science textbook (Life Science Library: Water (1966), by Luna B. Leopold and Kenneth S. Davis) points out that the temperatures at which water actually boils and freezes on earth are “out of the ordinary,” that they “do not fit the pattern set by similar compounds,” that they are “curiously out of step with chemical theory.” Of four similar compounds, “water, with the lowest of the four molecular weights, belongs at the bottom. Instead it is the highest of all.” It adds, “Happily for life on this planet water is the maverick in the group.”
Why? Why would there be an exception, which, with significant other exceptions, amount to a fine-tuning of our world, making our existence not only possible but comfortable? Providing not only potable water but forms of water that allow for iced drinks and cups of hot tea?
The “water window” is just one more example of the way in which our planet is “privileged” beyond the possibility of coincidence. Doesn’t it seem as if Someone prepared for our coming? One might say we are not only privileged but positively spoiled.
