I wanted to know how Einstein's General Relativity and its equations simplify to Newton's Universal Law. Einstein's equation is obviously a much more generalized version of Newton's law and gives much more accurate predictions that Newton's laws even if we don't think of Newton's gravity as spacetime warping.

On a side note, I've seen simulations of space time bending and demonstrations describing it as a trampoline with a ball in the middle causing a curvature of the space around it... if this analogy is accurate then how "stretchy" is the fabric of spacetime? The Sun is 99% the mass of our entire solar system so it must bend spacetime strongly and as far as Pluto to keep all the planets in orbit.
