 Mystery of Time If you can read a clock, you can know the time of day. But no one knows what time itself is. We cannot see it. We cannot touch it. We cannot hear it. We know it only by the way we mark its passing. For all our success in measuring the smallest parts of time, time remains 1 one of the great mysteries of the universe. In the real world -- the world with time -- changes never stop. Some changes happen only once in a while, like an eclipse 2 of the moon. Others happen repeatedly, like the rising and setting of the sun. Humans always have noted 3 natural events that repeat themselves. When people began to count such events, they began to measure time. In early human history, the only changes that seemed to repeat themselves evenly were the movements of objects in the sky. The most easily seen result of these movements was the difference between light and darkness. The appearance and disappearance 4 of the sun was even and unfailing. The periods of light and darkness it created were the first accepted periods of time. We have named each period of light and darkness -- one day.
