Who are the scientists who investigated gravity?

Several key scientists have made significant contributions to our understanding of gravity. Sir Isaac newton formulated the law of universal gravitation in the 17th century, describing gravity as a force that attracts two bodies with mass. In the 20th century, Albert Einstein revolutionized the concept with his general theory of relativity, which explains gravity as the curvature of spacetime caused by mass. Other notable figures include Galileo Galilei, who studied motion and falling bodies, and Johannes Kepler, who formulated the laws of planetary motion.
