I am pondering your explanation. The problem with singularities is that it is difficult to know what is inside. I'm not sure why you think we could be in a black hole now because the definition of black hole is a place where the orbital velocity for mass is greater than the speed of light (the definition of Schwartzchild radius or event horizon). There is no reason to believe that we have the mass density near us to cause such a curvature. My explanation (to my kids) was that a black hole was a cosmic vacuum cleaner. Anything that was near it became part of it. Further, I'd now say it didn't enclose "volume" in the sense that we ordinarily consider volume to exist. Outside is defined by what light does. Inside exists only as mass. To expand upon this, I think all of our notions of time and space become meaningless at a singularity. I disagree with your volume calculations because of the relativistic problems in doing so from one inertial frame (ours) to another (the black hole). If you were going near the speed of light and orbiting the black hole beyond the event horizon, you'd "see" a strip of blue-shifted x-ray light near you that vanished to the front of you (kind of a very thin triangular sliver). There would be no perceptible curvature. As you approached the event horizon, you would only see a line in front of you. If you jammed on the brakes and started to fall in, when you dropped below the event horizon you'd "see" everything away from the mass become a circle overhead (assuming you are dropping in feet first) and nothing anywhere else. The size of the circle overhead is related to the velocity as you drop in. The faster you drop the bigger the circle. But all of this implies that "you" could see. You are made of physical parts with finite strengths. I think such mind experiments are fun, but EXTREMELY misleading as to the world inside the black hole. Existence as we know it is not possible. Now if you hypothesize another set of universes inside the black hole erupting mass at a lower dimensionality, I could get behind that. Since we may have many dimensions, the loss of one of these dimensions could turn our "hole" into a "white gusher" in another universe. Back in the 60's it was thought that quasars might be such beasts. We still don't have particularly good models as to why there once were these energetic sources, but they no longer exist (anywhere we can see).
