During the Scientific Revolution of the 1500s, scientists like Copernicus, Kepler, Galileo, and Newton made important contributions that changed views of the universe and established the scientific method. Copernicus proposed that the Earth revolved around the Sun, contradicting the Church's teachings. Kepler proved Copernicus right and also discovered elliptical orbits. Galileo improved the telescope and made observations supporting Copernicus, but got in trouble with the Church. Newton discovered gravity and laws of motion and established classical mechanics. Their work fundamentally transformed science and thinking.
