His discoveries provided powerful evidence for the Copernican heliocentric model of the universe, which held that the Earth and other planets orbit around the Sun. This model was a major departure from the Aristotelian view of the cosmos, which held that the Earth was the center of the universe and that the stars and planets orbited around it. Galileo’s work helped to establish the scientific method and the importance of empirical evidence in testing hypotheses, and it paved the way for the scientific revolution of the 17th century.
