SUMMARY
Gravity is zero at the center of Earth due to the equal distribution of mass surrounding the center, resulting in gravitational forces canceling each other out. In contrast, at the center of a black hole, gravity is predicted to be infinite due to the singularity, where density becomes infinitely large and the laws of physics as we know them break down. The fundamental difference lies in the nature of mass distribution and the effects of general relativity in extreme conditions, as outlined in the equations governing black holes.
