Why is the ptolemaic system considered incorrect?

The Ptolemaic system is considered incorrect because it posits that the Earth is the center of the universe (geocentrism) and that all celestial bodies, including the Sun and stars, revolve around it in complex circular orbits. This model fails to accurately predict planetary positions and movements, leading to significant discrepancies. The heliocentric model proposed by Copernicus, which places the Sun at the center, provides a more accurate representation of the solar system and is supported by observations made by later astronomers like Galileo and Kepler. Ultimately, the Ptolemaic system was abandoned in favor of models that aligned better with empirical evidence.
