Why not Newton's gravity ?

Its just amazing How Newton's laws of gravity are, you can't give all credit to apple, that man worked his life for the advancement of science.

He found the law of gravity, calculus and other interesting things when he was quarantined for a year during plague in London. His work was celebrated for more than two centuries until Einstein gives his breakthrough paper in 1905.

Its a question everyone wants to ask "Why not Newton's gravity, Why can't it be enough" its obvious to ask such a question because newton's laws have taken us to Moon. So here is the problem, Newton and his laws on gravity are very good approximation of Einstein's theory for the objects we deal in our day to day life. But we need to understand that newton was never able to explain what gravity is, why should it exert a force and this rattled Einstein and also this was the question which helped him to come up with his theory of gravity. Einsteins approach of gravity is more of a mathematical one, where he explains why exactly there is gravity and no wonder his theory turns out to be true, Now we are able to discover gravitational waves, Black holes, and for matter of fact today's GPS system works on the principles of Einstein's special and general relativity.

So to conclude the Newton's gravity was only a good approximation of Einstein's theories, and maybe one day we will find theory of everything then we could say Einstein's theories were only a good approximation of a much greater picture of how we understand this universe.
