Gravity is the warping of spacetime by mass or energy. A mass like the Earth warps spacetime so that the shortest path, the “path of least resistance,” for inertial movement is towards the Earth’s center. Using instruments like the Hubble Space Telescope, it’s possible to literally see the warping of spacetime by very massive objects [...]
