Mass of a Black Hole
I don't think so- if it was "gone" it would not have mass, charge or spin. I don't think the term frozen is adequate as one no doubt could not see the black hole, let's say, hidden just at the event horizon, but the important point is that there is NOT a singularity in...
Einstein said when he was confronted with the notion of a singularity existing within a black hole that, should a singularity exist it would twist all of spacetime up within itself and therefore it could'nt be true that singularities existed within black holes.
Einstein was right...
There is a paradox- Relativity requires that you specify what your frame of reference is. A spaceship can go into a black hole- and will fairly rapidly be squished out of existence as all matter in the spaceship is accelerated towards the singularity at the centre of the black hole. This is...
Black holes certainly exist- what doesn't exist, yet, is the singularity within them. Black holes are thought of as- sort of- "frozen" in time from our viewpoint. See below. Black holes and singularities are two different beasts, though one is a consequence of the other. The singularity is in...
