The Scientific Revolution saw a dramatic change in scientific ideas as a result of several factors: the exchange of ideas during trade, universities studying ancient science again during the Middle Ages, and the interests in math and the human body during the Renaissance. Key figures like Copernicus, Galileo, and Newton helped overturn old ideas and models of the universe, with Copernicus and Galileo proposing that the Sun, not the Earth, is at the center of the universe, and Newton discovering the law of gravity. However, Galileo faced opposition from the Catholic Church for his findings that contradicted their teachings.
