My point of view

Isaac Newton only claimed that gravity was an attracting force between all objects because that's the way things appear --objects fall to the Earth or approach each other when floating in outer space. So Newton understandably claimed that it must be some type of attracting force emanating from objects,but he gave no scientific explanation for this force. Why does it attract and not repel? How does it cause falling objects andorbiting planets without drawing on any known power source?
Einstein was so dissatisfied with our lack of understandingabout gravity even two centuries after Newton that he inventedan entirely new theory of gravity as a warping of "four-dimensional space-time" known as General Relativity Theory.But this theory is even more mysterious and unexplained, and also suffers from the same problems as Newton's gravitationalforce theory. What is "four-dimensional space-time" and whywould the mere presence of matter warp it?
Where is the apparently unlimited power source for it all?
And, despite both Newton's and Einstein's attempts to explain gravity, we are still mystified by it today. Scientists are searching for "graviton particles" within the atom or "gravitywaves" rippling through deep space, hoping for some sort ofphysical verification for one gravitational theory or another.Meanwhile, they are inventing even further theories of gravity,such as Quantum Gravity and String Theory.

Frankly Speaking 'Gravity' is a complete mystery in our science even today
