Geocentric system, real or pure historical fantasy model? The geocentric system is an astronomical model which places the Earth at the center of the universe, and all other heavenly bodies would rotate around it.

This model was the predominant cosmological system in many ancient civilizations such as the Greek.

His most remarkable interpretations are to be to Aristotle and Ptolemy.

This geocentric theory was widely accepted for nearly two millennia until early modern when, after attempts to Tycho Brahe to adapt it to new discoveries with his Tychonic system, was eventually replaced by the heliocentric system of Nicolaus Copernicus revisited by Galileo Galilei and especially Johannes Kepler.

The geocentric system was proposed by the great Greek astronomer Eudoxus of Cnidus in accord with ideas of his teacher Plato and quickly replaced the archaic cosmography, which is implied in the works of Homer and the general lines of the Greeks shared with the peoples of the Near East. It eliminated the problem of establishing what it rested on the Earth. Now the point “lower” was the center of the Earth and the question did not make sense. Even in the East, a geocentric universe was adopted in Hindu texts of the Puranas, where the earth, at the center, was not considered the best place, but the only one where the man could get the “liberation.”

The geocentric system was accepted for nearly two millennia, but in the end, it was replaced by the heliocentric rational because the assumptions on which it held the first turned out to be erroneous, while the Copernican progressively endowed the new physics of Galileo and Newton.

Aristotelian cosmology, in fact, entered into crisis because of the first observations with the telescope, which revealed strong similarities with that of the celestial world sublunar: Galileo, using telescopes of its construction was discovered that the Moon had mountains, spots Sun, Venus had phases and therefore shone with reflected light as the moon.

If the sky was so similar to Earth there was no scandal to the hypothesis that the Earth was a planet like the others.
