Why “Gravity” Does Not Exist
Newton said gravity is a mysterious force that affects everything with mass. He didn't know what causes this force but he did create some useful equations. Then Einstein came up with General Relativity.
The Short Answer
Newton said gravity is a mysterious force that affects everything with mass. He didn't know what causes this force but he did create some useful equations. Then Einstein came up with General Relativity. He says that mass bends space-time and that's why things are attracted to each other. For Example, if you put 2 heavy balls on a trampoline, they warp the trampoline and move towards each other. This is just an analogy, but it helps give you the idea. This warping of space-time has some other side affects, which allows General Relativity to predict and explain thing that Newton's law doesn't (like small changes in the orbit of planets, light bending around stars, and clocks in GPS satellites running slower).
