This paper briefly discusses how for thousands of years, scientists have attempted to explain the phenomenon of gravity in various ways. Gravity is one of the four fundamental interactions of the universe, yet arguably less is known about it than any of the other three forces. The paper briefly examines theories from Aristotle and Galileo to Sir Isaac Newton and Albert Einstein and explains that the current view of gravity as a "universal glue" helps to explain the basic motion of our solar system and the universe as a whole.
From the Paper:"To the Greek philosopher Aristotle, gravitas was an internal property of the four classical elements and not an external force. Because he believed no effect or motion occurred without a cause, Aristotle hypothesized that substances moved according to their nature. The heavier elements, earth and water, had positive densities. Thus, their motion was naturally directed downward to the center of the universe. The lighter elements, air and fire, had negative densities that caused them to move upward to the heavens (Gregory 3). The Roman engineer Vitruvius later proposed that the property of gravitas did not depend on the weight of object but upon its nature."
