Newton’s theory suggests it’s close to zero, but what says GR?
Edit 1: It’s obvious that at the center it’s zero for both theories. The curvature explanation of GR could give a different answer around the center. I mean expecting that curvature goes steeper around the center is more natural to me. Is this interpretation discussed before?
Edit 2: But why this interpretation?
Because of the pressure, things get denser. As density increases curvature gets steeper.
