%X The singularity at distance <i>r</i> ¡ú 0 at the center of a spherically symmetric non-rotating, uncharged mass of radius R, is considered here. Under inverse square law force, the Schwarzschild metric, needs to be modified, to include Newton¡¯s Shell Theorem (NST). By including NST for <i>r</i>£¼<i>R</i>, both Schwarzschild singularity at <i>r</i> = 2<i>GM</i>/<i>c</i><sup>2</sup> and at <i>r</i> ¡ú 0 singularities are removed from the metric. Near <i>R</i> ¡ú 0, the question of maximal density is considered based on Schwarzschild¡¯s modified metric, and compared to the quantum limit of maximal mass density put by Planck¡¯s quantum-based universal units. It is asserted, that General relativity, when combined with Planck¡¯s universal units, inevitably leads to quantization of gravity.
