Your misinformed."....anyone who has studied Newton's account of gravity and Euler's account of gravitational energy will have to gulp. Their nonrelativistic viewpoint distinguished two forms of energy. One form, 'kinetic, depended on speed, not distance from the center of attraction. The other form, 'potential', depended on distance from the center of attraction, not speed. Einstein's account of motion in curved spacetime recognizes no such distinction. This new outlook presents us with a new unity. Energy associated with speed, energy associated with location, and energy associated with mass are stirred together inextricably into a greater and simpler whole."

This following statement of yours is bs
"The Schwarzschild approximation assumes that for an orbital object, the potential energy is small compared to its mass and this results in an error at small r. So the Schwarzschild solution is not a good model for a black hole. It is even off slightly for the precession of the perihelion of Mercury."
You, and whoever your copying such bs from, are the ones making assumptions.
