What are the differences Between Einstein view on Gravity and Newton view on Gravity ?
Newton’s model of gravity is inconsistent with relativity–it supposes that masses act on each other with forces that propagate instantly over the distance between the masses. In Einstein’s model, the effects of gravity are local–they propagate from one mass to the other at light speed. Just as accelerating charges produce electromagnetic waves, accelerating masses should produce gravitational waves. We ought to soon be able to detect such waves from violent events like supernovae. We can already indirectly infer their existence by the energy they carry off from certain systems. Einstein modeled gravity as a warping of space/time by large concentrations of mass/energy. Rather than a gravitational force pulling on an object to make it follow a curved path, you can think of the object moving in a straight line in a warped space, which thereby appears to be a curved path. This technique correctly predicts the path that light will follow around a massive object, which classical gravitatio
