Learn how gravity can be described by the curving of spacetime, in this video from NOVA: Black Hole Apocalypse. According to Einstein’s general theory of relativity, all objects curve spacetime around them; the more massive an object, the more it curves spacetime and influences other nearby objects. When objects fall, they travel along these curves in space. Computer animations illustrate the concept of warped spacetime and how objects “fall” along a curved path.
