Answer: Copernicus proved that the Sun is the center of the universe
Explanation: Nicolaus Copernicus (19 February 1473 - 24 May 1543) was a Polish astronomer and mathematician who set up a model by which the Sun is the center of the universe, not the earth. At that, the planets of the solar system do not rotate around the earth, but around the sun. He was condemned by the Church as a heretic, although he contributed to the development of the Scientific Revolution by his work.
