By proposing that the Earth and planets orbit the Sun, he challenged the long-standing geocentric model endorsed by the Church. Copernicus studied law and medicine but devoted his life to mathematics and astronomy, undertaking precise observations and calculations. His theories laid the foundation for the Scientific Revolution and influenced future luminaries like Galileo, Kepler, and Newton.
