For centuries, the prevailing view was that the Earth was the center of the universe, with all other celestial bodies revolving around it. This was known as the geocentric model, supported by philosophers like Aristotle and Ptolemy.
However, observations made by astronomers like Nicolaus Copernicus and Galileo Galilei challenged this theory. Through meticulous observations and calculations, they discovered that the Earth actually revolves around the Sun, not the other way around. This led to the development of the heliocentric model, a groundbreaking shift in our understanding of the universe.
The transition from the geocentric to the heliocentric model is a prime example of how new observations can overturn long-held scientific theories and pave the way for new discoveries.
