Final answer:
Galileo believed in a heliocentric view of the universe, which states that the Sun is at the center of the solar system and the planets revolve around it.
Step-by-step explanation:
Galileo believed in a heliocentric view of the universe. The heliocentric model states that the Sun is at the center of the solar system, and the planets, including Earth, revolve around it. This model is in contrast to the geocentric or Earth-centered view, which was predominant before the discoveries of scientists like Copernicus, Galileo, and Newton. The heliocentric model provided a simpler explanation for the motions of celestial bodies and was supported by scientific observations and laws of physics, such as Newton's universal law of gravitation.
Galileo Galilei was a proponent of the heliocentric view of the universe, challenging the prevailing geocentric model where Earth was considered the center. The heliocentric model, established by astronomers like Copernicus and later refined by Galileo and Newton, posits that the Sun is at the center of the solar system, with planets, including Earth, orbiting around it. This paradigm shift revolutionized our understanding of the cosmos. The heliocentric model provided a more straightforward and elegant explanation for the apparent motions of celestial bodies, aligning with empirical observations and principles like Newton's universal law of gravitation. Galileo's telescopic observations, such as the phases of Venus and the moons of Jupiter, provided compelling evidence supporting the heliocentric model and played a pivotal role in the scientific revolution of the 17th century.
