Idealistic solution for non-rotating BH includes a "white hole part" However, realistic solution is different For the rotating BH we have an ideal solution with an "eternal" ring singularity inside, which can't be realistic, as ring, as I said, is "eternal" and there is no transition of collapsing matter into that ring. So for the rotating BH we I know only the "idealistic" picture. The questions I have: 1. Is there any progress on that subject? 2. Can it be solved, in principle, without taking QM into account (as QM can be preventing spacetime from forming CTLs) 3. Even not taking QM into account, what is a difference between the rotating BH in standard GR and Einstein–Cartan theory? How far that difference "propagate"? Does it propagate to the exterior of BH?
