Gravitational physics is the branch of physics that focuses on the study of gravity, its effects, and its interactions with matter and energy. This field encompasses the theory of general relativity, which describes how mass and energy curve spacetime, and the behavior of objects in this curved space. Gravitational physics also includes the study of gravitational waves, which are ripples in spacetime produced by accelerating masses, and the nature of black holes, which are regions of spacetime where gravity is so strong that nothing can escape, not even light. Research in gravitational physics seeks to deepen our understanding of these phenomena and their implications for the universe as a whole.
