the Sun, rather than the Earth. This heliocentric model fundamentally changed the understanding of the cosmos.
Nicolaus Copernicus proposed the idea that the Sun was at the center of the universe, with Earth and other planets revolving around it. Johannes Kepler later built on Copernicus’s work, formulating his three laws of planetary motion, which provided a mathematical foundation for the heliocentric model, showing that planets move in elliptical orbits rather than perfect circles.
Galileo Galilei, using his telescope, made several critical observations—such as the moons of Jupiter and the phases of Venus—that supported the heliocentric theory and challenged the prevailing geocentric view. Together, these scientists helped to revolutionize astronomy and laid the groundwork for modern science.
