Earth was the center of the universe
According to Aristotle the Universe is a sphere and Earth is at the centre.
Ptolemy's biggest discovery was his geocentric model of the universe, which believed that the Earth was at the center of the universe with planets and stars moving around it in circular orbits. This model dominated Western astronomy for over a thousand years.
Ptolemy's model is different from the earlier Greek model because Ptolemy developed a compllex geocentric model of the universe and his model seemed to explain motions until the 1500s.The early Greek astronomers believed that Earth was 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.
Scientists such as Nicolaus Copernicus and Galileo Galilei developed ideas that contradicted Ptolemy's geocentric model of the universe. Copernicus proposed a heliocentric model with the sun at the center, while Galileo's observations through a telescope supported this idea, leading to the eventual acceptance of the heliocentric model.

The geocentric model stated that Earth was the center of the universe, and all other bodies revolved around it.Ptolemy thought that the rest of the universe spun in nested circles around the Earth, with the Sun and stars much closer than they actually are.
