I have been doing some thinking about the collapse process inside a rotating black hole. (I think that the probability of creating a non rotating black hole with its point singularity and awkward infinities is so unlikely as to be not worth bothering about). Note this analysis requires no new physics whatsoever. Just standard relativity quantum theory and gravity. This is how I visualise it. Initially conditions will not be too far different from those found and analysed in our universe particularly if the hole is a massive one. There will be an initial ellipsoidal collapse and adiabatic heating which will become toroidal as "viscosity" drags the still center out and gives it angular momentum. As the collapse to a ring continues residual angular momenum about the ring will cause it to rotate like a smoke ring and again the residual still centre of the torus will be evacuated. so the final stucture is a rotating toroidal membrane which allows angular momentum in all dimensions to be accommadated The particles and photons that formed the hole will settle down into a massive toroidal structure that rotates at speeds approaching the speed of light (ie many times the rest mass of any particles) but the individual particles will cool down relative to each other and become relatively quiet in spiral orbits around the centre where a massive gravity gradient holds the whole thing together. This spiral will also stabilise itself and the whole structure will be a bit like a smoke ring with the particles very close together but with very similar directions and velocities. What would the universe look like to a particle in this ring singularity inside a rotating black hole during this settling down process? Let us assume that the hole is quiet and isolated from anything else so there is no new material coming in. so there is nothing to see outside the singularity My feeling is that when one looks from an individual particle to its near companions that taking in the spacetime dilations caused by the extreme velocity and gravity gradients the immediate surroundings would look very much like normal flat three dimensional empty space with the possibility of evolutional cooling clustering and structuring coming as a time dimension. Also that the gradual cooling of the material would result in an increase in velocity and gravitational gradient that will make the volume of space appear to expand with time. This is because an object in a freefall orbit is totally unaware of any motion due to the orbit and, in the absence of any distant fixed points, can only be aware of its relative movements with respect to its neighbours. also as the initially random motions of the particles settle down the orbital energy and gravitational gradients will steadily increase. If this IS so, it could unleash the wildest model of our universe that you could ever imagine. That is, that the whole of space itself could be a "fiction" created by the kinetic and gravitational energy of the black hole and that in one dimension everything IS very close together! This could also provide simple classical explanations of quantum wierdness that says all particles exist in all space at all times because even for a large rotating black hole this central ring singularity would be very small indeed. The high orbital energy would also explain the behaviour of the quantum mechanical vaccum when interactios allow this to be accessed One final note if the black hole was slowly evaporating this wouuld cause a slow loss of energy from the singularity which i think would cause the perception of space to increase in size a bit more than one might expect! One interesting feature of this hypothesis is that it is like Fred Hoyle's continuous creation hypothesis quite possible to refute but at the same time provides a totally consitent and continuous structure for a multiverse. On the largest scale our universe would therefore be toroidal with the possibility of having recursion (seeing the back of your own head in the distance) and some of the latest results of cosmic microwave background correlations suggest that this may not be an unreasonable idea. I have tried to find if anone else has analysed this situation and also how orbits behave in extreme relatavistic conditiond bit so far have failed so I thought it might be worth while putting this up for comment here.
