General relativity predicts that the presence of matter and energy curves the fabric of spacetime, resulting in the phenomenon of spacetime curvature. The curvature of spacetime determines the motion of objects in the vicinity of massive objects such as planets, stars, and black holes. In the absence of gravity, objects follow straight paths in spacetime, but in the presence of gravity, these paths are curved. The curvature of spacetime predicted by General relativity has been confirmed by numerous experiments, and it is a fundamental concept in our understanding of the behavior of gravity and the universe as a whole.\n
How does General relativity relate to the concept of spacetime curvature?
