Aristotle argued that the universe is spherical and finite. Spherical, because that is the most perfect shape; finite, because it has a center, viz. the center of the earth, and a body with a center cannot be infinite. He believed that the earth, too, is a sphere. It is relatively small compared to the stars, and in contrast to the celestial bodies, always at rest. For one of his proofs of this latter point, he referred to an empirically testable fact: if the earth were in motion, an observer on it would see the fixed stars as moving, just as he now observes the planets as moving, that is from a stationary earth. However, since this is not the case, the earth must be at rest. To prove that the earth is a sphere, he produced the argument that all earthly substances move towards the center, and thus would eventually have to form a sphere. He also used evidence based on observation. If the earth were not spherical, lunar eclipses would not show segments with a curved outline. Furthermore, when one travels northward or southward, one does not see the same stars at night, nor do they occupy the same positions in the sky. That the celestial bodies must also be spherical in shape, can be determined by observation. In the case of the stars, Aristotle argued that they would have to be spherical, as this shape, which is the most perfect, allows them to retain their positions.
Aristotle, like Eudoxus and Callippus before him, believed that each planet followed the path laid out by a certain number of spheres. Callippus had postulated 33 spheres in all, 4 each for Saturn and Jupiter, 5 each for Mars, Venus, Mercury, the sun and the moon. The problem with this model, however, was that, according to Aristotle, it did not explain how the motion of the outer spheres was to be prevented from interfering with the motion of the inner spheres. Aristotle therefore attempted a mechanical explanation, and postulated 22 counteracting spheres, which would set things in balance. It is generally held that Aristotle's addition of these counteracting spheres complicated rather than cleared up the problem of planetary motion.
At the center of Aristotle's model was the concept of the unmoved mover, which served as the ultimate cause and source of motion in the universe. It was an eternal, unchanging being that set everything in motion without being moved itself.
Aristotle believed that the Earth was at the center of the universe, with all other celestial bodies revolving around it in a series of concentric spheres. This geocentric view of the universe contrasted with the later heliocentric model proposed by Copernicus.
Rene Descartes viewed the universe as a mechanical system governed by natural laws. He believed that everything could be explained through mathematics and that the physical world operated like a giant machine. Descartes' view was heavily influenced by his mechanistic philosophy and his belief in the power of reason and understanding.
Pythias, the daughter of Aristotle& Pythias .
Demetrius, Hermiala, and Vermus were Aristotle's siblings.
According to Aristotle the Universe is a sphere and Earth is at the centre.
he thought the earth was the center of the universe and the sun and the planets orbiting the earth. but he was wrong.
The view that the earth is the center of the universe.
Aristotle's model of the universe took into account the charted movements of the heavenly bodies, but was complicated by the assumption that Earth lay at the center of the universe.
The Icelandic view of the universe described by Sturluson talks about the universe in which the giants and the gods battle.
