Quizplus · Accepted Answer

Nicholas Copernicus is widely known as the first person to challenge the Ptolemaic system of the universe, which placed the earth at the center of the universe. In his work "On the Revolutions of the Heavenly Spheres", Copernicus proposed a heliocentric model where the sun was at the center of the universe and the Earth and other planets revolved around it. This was a groundbreaking theory that paved the way for other astronomers, such as Galileo Galilei and Johannes Kepler, to further develop and refine the heliocentric model.
