Gravity, according to General Relativity (GR), is defined as the curvature of spacetime caused by mass and energy. This concept fundamentally shifts the understanding of gravity from a force to a geometric property of spacetime. The technical definition emphasizes that massive objects like planets and stars warp the fabric of spacetime, influencing the motion of other objects. For a comprehensive understanding, refer to resources such as the "No Nonsense Introduction to General Relativity" available at Preposterous Universe.
