The Prevention of Singularities Inside Black Holes
  In this paper the currently held view that the endpoint of gravitational collapse is a singularity is refuted. A quantum mechanical calculation is done showing that spin 0 and spin 1/2 particles inside a black hole's schwarzschild radius aren't confined to an infinitesimal point but form bound state orbits. As with the case of electric collapse, if an electron cannot spiral into a nucleus, then neither does this happen in plasma consisting of many electrons and nuclei. Showing that after undergoing gravitational collapse, like plasma, matter will not contract to an infinitesimal point. That quantum effects prevent singularity formation.
