Einstein's view of gravity is not a force of attraction between matter, but a natural consequence of curved space and time caused by mass. Einstein's extraordinary claim is that there is no force of attraction between the Earth and moon; it is simply the moon following curved spacetime. en.wikipedia.org/wiki/Gra…
