Long age, Earth was the subject of great speculation. Ancient astronomers such as Ptolemy thought that Earth was the center of the universe. Likewise, there have been all sorts of assumptions about Earth's satellite, the Moon. One of the most interesting beliefs was that moonlight was capable of driving a person crazy. Using a telescope, Galileo Galilei went on the show that the Sun was actually the center of the universe. And while some folks still believe that a full Moon brings out the "weird" in people, they have plenty of solid evidence that proves the Moon has real natural effects on Earth. For instance, the gravitational pull of the Moon during its many phases influences ocean tides. Many additional facts about Earth and the Moon have been discovered over the years. The results of years of research into the nature of Earth and the Moon are the subject of this book.
