Welcome to class. I'd like to introduce myself as Professor Jesuit. I teach the subject theology at the College of Rome. This week you all will be learning about Aristotle's view of the world and heavens. You will also be leaving class with solid facts and reasoning as to why the Aristotelian view is correct and why Galileo's proposed view is incorrect and has no solid basis. Please pay close attention so that you all may become aware of the truth about the world we live in. 
Firstly, we will discuss Aristotle's view on the motion of the earth and heavens. Aristotle proposed his perception of the Earth and Heavens after studying and understanding the concept of motion. He proposed that the only motion that is eternal is circular. Celestial bodies move in circular motion as well as the heavens. It is a fixed motion. However, the earthly realm is different from the heavenly realm. Anything that consists of earth and water moves on its own; either straight down or straight up. On the other hand, in the heavenly realm everything moves in a circular pattern. Aristotle suggests that everything in the heaven is attached to glassy globes which enforce the rotations of the sun, moon, he avens, and planets around Earth; w hereas, the Earth does not move. As I stated earlier, Aristotle proposed that in the earthly realm either the motion of things is straight up or straight down. These forces are represented by the elements. Earth and water moving in a straight downward motion and air and fire move in a straight upward motion. If any external force acts upon the object it can alter the motion slightly but the external force will eventually die out and the natural force will be enforced again. This is referred to as "Violent motion" by Aristotle, in which a n external force alters the natural motion of an object in the earthly realm. For example, wind can be considered an external force that alters the motion of an object, but eventually the wind will top and the object will fall into its natural motion of either straight up or down. However, if the Earth was rotating then everything made up of earth and water would also move in a circular motion, which it clearly does not. Since everything on the earth moves in a straight motion towards the center of the Earth, it is simply not possible for the Earth to be moving in a circular motion. Up and down are motions that contradict one another and eventually come to an end, making them imperfect; t herefore, proving that the contradicting perfect motion is circular. This brings me to my second argument that since the earthly realm is in natural motion of up and down, the heavenly realm must be in a constant circular motion. 

Aristotle proposed that heavenly bodies such as the Sun and Moon are in the shape of perfect spheres. The heavens are fixed and immutable. They are "eternal and unchanging" according to Aristotle. Additionally, there is only one universe in which the heavens do not change or decay. The Aristotelean view of the heavens being in circular motion is proved by the facts that up and down motions are natural on earth but are considered to be unnatural in the heavens. Earthly motions come to an end; whereas, circular motion has no end or opposite. Since a circle is a perfect sphere with no bumps or ridges it cannot subject to change. In order for change to occur there must be an interaction between opposites, which are nonexistent in circular motion. This non-changing, perfect heavenly realm suggests that it is eternal like the gods. Our realms are distinguished because one is perfect and the other is imperfect. This leads to a bigger idea that there is another force that is controlling this. The Aristotelian view is backed up by the evidence that there has been no reported change in the heavens. Aristotle also believes that the heaven is not infinite in size. It has been proven that the sphere of stars turn a finite amount of times; whereas, if
