Question: 1 / 2010

Which astronomer proposed the heliocentric theory?

Johannes Kepler

Isaac Newton

Nicholas Copernicus

The heliocentric theory, which posits that the Earth and other planets revolve around the Sun, was proposed by Nicolaus Copernicus in the 16th century. He challenged the prevailing geocentric model, which held that the Earth was the center of the universe. Copernicus's idea was revolutionary as it shifted the perspective of celestial mechanics and paved the way for modern astronomy. His work laid the foundation for later astronomers, such as Galileo and Kepler, who built upon and provided further evidence for the heliocentric layout of the solar system. This theory not only transformed scientific thought but also had profound implications for philosophy and the understanding of humanity's place in the universe.
