Aristotelian
In Aristotelian cosmology, earth is the center of the universe, and all the planets, stars, sun, and all the heavenly bodies revolve around the earth.
Aristotle believed that earth is eternally unmoved and everything else revolves around it in concentric spheres. In fact, Aristotle’s view of the universe was widely accepted from its inception until the emergence of the scientific revolution. (Don’t worry, we will talk about it in the later section). Although, Aristotelian principle was widely accepted by scientists and philosophers of his time. Yet, there were some who openly criticized Aristotle beliefs.
Aristotle believed that the sphere of stars was moved by the prime mover. On the other hand, all the other heavenly spheres were moved by the unmoved mover. Meaning, in Aristotelian universe, the prime mover moved the stars. And in return, the unmoved mover moved all the other celestial spheres (without interfering in the mechanics of each other).
Therefore, Aristotle believed that all the heavenly spheres were somehow related to each other. Though, he never gave the explanation that what was the prime mover or the unmoved mover.
