7. More specifically, the Non-Euclidean Geometry devised by Bernhardt Reimann. This is the geometry of curved surfaces, like the surface of earth'.

And by "Geometry" we should understand that it is not the Euclidean Geometry (geometry of flat surfaces) , but the Non-Euclidean Geometry

US Physicist James B Hartle of University of California, Santa Barbara writes, "The central idea of General Theory of Relativity is that gravity arises from the curvature of spacetime. Gravity is Geometry."

5. The delay is because, the experiment could be conducted and the deflection could be measured only during a solar eclipse.

The most important aspect of the theory was that, it predicted a measurable result. This prediction proved correct by an experiment conducted independently, by scientists, much later.

4. In 1911, he wrote that gravity will influence propagation of light. "A ray of light going past the sun would undergo a deflection of 0.83 seconds of arc (a second is 1/3600 of a degree) . He later revised the theory which predicted that the bending would be twice that was predicted earlier.

After over four years of rigorous work, Einstein came up with Field Theory of Gravity in November 1915, which would help him generalise Relativity.

Einstein had formulated Th Special Theory of Relativity in 1905. When he understood the limitations of the theory and it's possibilities he wanted to formulate a General Theory of Relativity which could include gravity.

I am a student of Physics and of the firm opinion that Physics (with a capital'P') is the mother of all sciences.
