I'm writing this essay to explain to people interested in gravitation how it works according to Einsteinian physics.  

Between 1905 and 1915 the theory of gravitation switched from Newtonian math to Einsteinian physics and many Newton's problems got solved, mostly due to the fact that the space is not flat ("flat space" means the same as "Euclidean space"<ref>"Flat" or "Euclidean" means our regular (x,y,z) space in which a sphere of surface area <math>4\pi r^3</math> contains volume of space <math>4\pi r^3/3</math>.</ref> but is curved having certain [[curvatures of spacetime]] and besides, the time reflects faithfully these [[curvatures of spacetime]] through the gravitational [[time dilation]].

This essay is meant to explain this strange physics, with which we deal every day but, except for some people, don't know how it operates and where the "gravitational force" is coming from.
