All through history people have asked the same questions, like “What's for dinner?” and “Why do things fall?” Aristotle, who lived in Athens almost 2,500 years ago, argued that the center of the Earth was the center of the universe. So naturally everything tended to fall in that direction! Wrong on TWO counts. He also thought that heavier things fell faster than lighter things. Well, you could see how he would think that.
Try dropping a piece of paper and a book. The book hit the floor first, right? But not because of gravity and not because it is heavier.
Discuss.
