Which scientific revolution figure published his heliocentric theory in 1543?
Answer
Nicolaus Copernicus
Nicolaus Copernicus published his heliocentric theory in De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres) in 1543, proposing that the sun, not the Earth, was the center of the solar system. This revolutionary idea contradicted the geocentric model that had dominated Western thought for centuries and the teachings of the Catholic Church. Copernicus's work laid the foundation for the Scientific Revolution and was further developed by later astronomers like Galileo and Kepler.
💡 Did you know?
Copernicus delayed publishing his heliocentric theory for decades due to fear of religious persecution and criticism from the scientific establishment.
