The effects due to nonlinearity of Einstein's field equations is going to be negligible (and is ignored in these graphs).I am not saying they are not negligible.Ah, but they are. Unless you're planning on replacing general relativity with your own theory.

Woo Hoo and there is the Earth's Scwarzschild gravity well.
Ok, Jeffrey. But if you're going to be publishing plots of your own calculations without telling us what you're doing, could you please keep it to the New Theories section? This part of the forum is for open discussion of the science behind "mainstream" ideas in physics, such as Einstein's field equations or Newtonian gravity.
The latter graph seems to show the escape velocity decreasing when you reach 10m from the center of the Earth.Assuming a spherically symmetric Earth, the gravitational force would be the attraction of a 10m radius sphere (possibly with a significant content of gold, osmium or other dense materials). You would be effectively weightless (if you weren't instantly crushed by thousands of kilometers of iron and rock).This 10m radius sphere does not have enough density to form a black hole.I think the graphed reduction of escape velocity near the center of the Earth is a real effect - I think it might be some sort of underflow error.
