The singularity is a point with zero volume, but does it contain all the black hole mass? Are the singularities of a 1e3 solar mass and 1e10 solar mass black hole different? If a black hole acquires mass by slurping a star then does the stars mass instantly add to the singularity? And then is the space between the event horizon and singularity just empty? It doesn't make sense. Also, is there a chance that a black hole is just a 'normal' object like a neutron star, that happens to be too heavy to reflect or emit light?
