Gravitational Physics is the branch of physics that studies the force of gravity and its effects on matter. It encompasses the laws governing the attraction between masses, as described by Isaac Newton and later refined by Albert Einstein in his theory of General Relativity. This field helps us understand how celestial bodies interact and the structure of the universe. The study of gravitational physics is crucial for explaining phenomena such as black holes, gravitational waves, and the expansion of the universe. By exploring these concepts, scientists can gain insights into the fundamental workings of the cosmos and the nature of space and time.
