Detailed explanation-1: -The key difference between Einstein and Newton gravity is that Einstein described that gravity is a curvature in a 4-dimensional space-time fabric proportional to object masses, whereas Newton described gravity as a force expressed mutually between two objects in relation to their masses.
Detailed explanation-2: -He theorized that a mass can prod space plenty. It can warp it, bend it, push it, or pull it. Gravity was just a natural outcome of a mass’s existence in space (Einstein had, with his 1905 Special Theory of Relativity, added time as a fourth dimension to space, calling the result space-time.
Detailed explanation-3: -Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. That curvature is dynamical, moving as those objects move. In Einstein’s view of the world, gravity is the curvature of spacetime caused by massive objects. Image source: T.
