““I likewise thought—when I was solemnly first introduced to it at the age of thirteen—that “science” had fully explained the motions of the planets, the law of gravity, and the mysteries of time. Anything that had not yet been explained would no doubt soon be discovered. There were no mysteries. Because we could observe gravity in action, we somehow knew what it was. Nobody then mentioned that its operation, especially in empty space, simply cannot be explained. All was settled.””
