Edgar, Regarding " Nobody actually knows what happens in the singularity itself", Poplawski using Einstein equations with spin has determined what happens inside a black hole:
"In 2011, Nikodem Popławski<http://en.wikipedia.org/wiki/Nikodem_Pop%C5%82awski> showed that a nonsingular Big Bounce appears naturally in the Einstein-Cartan<http://en.wikipedia.org/wiki/Einstein%E2%80%93Cartan_theory>-Sciama-Kibble theory of gravity.[7] <http://en.wikipedia.org/wiki/Big_Bounce#cite_note-7> This theory extends general relativity by removing a constraint of the symmetry of the affine connection and regarding its antisymmetric part, the torsion tensor <http://en.wikipedia.org/wiki/Torsion_tensor>, as a dynamical variable. The minimal coupling between torsion and Dirac spinors generates a spin-spin interaction which is significant in fermionic matter at extremely high densities. Such an interaction averts the unphysical Big Bang singularity, replacing it with a cusp-like bounce at a finite minimum scale factor, before which the Universe was contracting. This scenario also explains why the present Universe at largest scales appears spatially flat, homogeneous and isotropic, providing a physical alternative to cosmic inflation." http://en.wikipedia.org/wiki/Big_Bounce Richard On Sun, Jan 26, 2014 at 12:41 PM, Edgar L.
