Heavenly Errors: Misconceptions about the Real Nature of the Universe

This book refutes many fond misconceptions of the universe, such as "twinkling" stars, our Sun always rising directly in the East and only the Moon causing tides. Next, though it is not addressed in this book, we'll be told the Earth isn't flat and it doesn't rest of the back of a giant turtle, which stands on the back of an even larger turtle, which stands on an even larger turtle ... and so forth ALL THE WAY DOWN. Comins misses the whole point about popular delusions. It's not that some of our most cherished beliefs are wrong; it's "Why do we get such nonsense and how do we survive with so many wrong ideas"? For example: The light from stars really does "twinkle", just as the nursery rhyme says. The U.S. military believed this, so DARPA sponsored research to eliminate twinkles. It was so successful that the procedure is now used to eliminate the "twinkle" when using optical telescopes at places such as Kitt Peak observatory, near Tucson. Two conclusions may be drawn: a) the starlight we see really does twinkle, and b) there's a good scientific reason for it. Comins emphasizes solid scientific facts for the myths he demolishes, which is commendable. He offers intelligent explanations of the universe as it is now known. Some of his examples seem trivial; but, sometimes it is precisely minor errors that grow into major misconceptions. His deft demolishing of myths many people have about the earth, moon, stars and the universe -- all physical realities -- raises an even more interesting question: "If people are so credible, how can democracy exist?" Perhaps the answer is something akin to the "missing" 96 percent of the universe -- Democracy, like the universe, is simply beyond belief, but if you believe, it works. Wait a moment: Isn't that what he set out to disprove? It's worth remembering when hearing politicians, used car salesmen and astronomers; people always seek answers, real or imaginary. We really do see twinkling stars, but it's not what it seems on first glance. It's the most valuable lesson you can take away from this book.
