Galileo Galilei and His Contributions

Galileo Galilei, an Italian physicist and astronomer, challenged the Aristotelian worldview by proving through experiments that all objects fall at the same rate, regardless of weight. He refuted the geocentric model by discovering Jupiter's moons, showing celestial bodies can orbit other planets. Despite his findings supporting heliocentrism, he faced opposition from the Church and was placed under house arrest. His work laid the foundation for modern physics and the scientific method.
