I'm a novice. As I understand it black holes gravitationally attract and 'consume' matter. Some black holes are small (>8 x sun masses), and some are supermassive (>100,000 x sun masses). If black holes ultimately contract to a singularity, presumably each time an object is 'consumed' it 'contracts' down to the singularity. Does all the gravity in a black hole then emanate from the singularity? Can you have a supermassive singularity?
According to General Relativity, the singularity has zero volume yet contains all the mass of the black hole. The appearance of a singularity in the solution may simply indicate the breakdown of the theory and it may be true that a theory which took quantum effects into account might not produce a singularity.
Thanks. So, all the mass is in there somewhere, but the singularity is, academically, a moot point.
