“To human eyes turned toward the sky 100,000 years ago, they appeared identical in size, as they do to our eyes today. In a total solar eclipse, the disc of the moon fits so precisely over that of the sun that the naked eye can see solar flares leaping into space from behind. But while they appear precisely the same size to terrestrial observers, scientists long ago determined that the true diameter of the sun is about four hundred times that of the moon. Yet incredibly, the sun’s distance from Earth is roughly four hundred times that of the moon’s, thus bringing them into unlikely balance when viewed from the only planet with anyone around to notice.22 Some will say, “Interesting coincidence.” Others will wonder whether there isn’t an extraordinary message contained in this celestial convergence of difference and similarity, intimacy and distance, rhythmic constancy and cyclical change. Like our distant ancestors, we watch the eternal dance of our sun and our moon, looking for clues to the nature of man and woman, masculine and feminine here at home.”
