The first scientist to dispute the geocentric model of the universe, which posited the Earth at the center, was Nicolaus Copernicus. In the early 16th century, he proposed the heliocentric model, which placed the Sun at the center of the universe, challenging the long-held views of Aristotle and Ptolemy. His seminal work, "De revolutionibus orbium coelestium," published in 1543, laid the foundation for modern astronomy and shifted the paradigm of celestial mechanics.
The first scientist to dispute Ptolemy's geocentric model was Nicolaus Copernicus. In the early 16th century, Copernicus proposed a heliocentric model, placing the Sun at the center of the universe and suggesting that the Earth and other planets revolve around it. His work, particularly the publication of "De revolutionibus orbium coelestium" in 1543, laid the groundwork for the Scientific Revolution and fundamentally changed our understanding of the cosmos.
