The Geocentric Theory, developed in ancient times, posited that the Earth was the central and stationary point of the universe, with celestial bodies, including the Sun and planets, revolving around it.
This geocentric model dominated scientific thought for centuries, notably advocated by Ptolemy.
It was later replaced by the Heliocentric Theory, proposed by Copernicus and refined by Kepler and Galileo, which asserted that the Sun, not the Earth, was at the center of the solar system.
This paradigm shift marked a crucial advancement in understanding the cosmos and laid the foundation for modern astronomy.
