I have posted stuff indicating the orthogonal time of a black hole tunnel (similar to Carlo Rovielli's idea - with a difference) and stating that time does not point toward a singularity. Then I realised that a black hole is likely a hypersphere. If it is that changes everything.
Although a BH may grow larger (expand) the surface is still 3D and as if onion layers, 3D continues toward a theoretical singularity. Orthogonal time then points toward a theoretical singularity except that the sphere is not singular. More a 4D torus perhaps or simply a very small hypersphere.
This suggests that the solution somehow depends on a reversal of the direction of time. Apart from that I have nothing to add - yet. Maybe everyone thought this was the case in the first place (?)
