Not convenient at all, but logic and common sense, which you seem to have let fly out the window. Maybe at this time you need to drop your pretense about knowing anything about BH's, for reasons not the least being, you doubt their existence, yet are unable to suggest any other entity or scenario that could have the same effects on spacetime, matter/energy that we observe. Despite your continued ducking and weaving of the many questions put to you, and the pretentious nonsense you babble on about, you are yet unable to explain how we have observational evidence of frame dragging/ergosphere, without a spinning mass..... Again, let me inform you that no professor, no link [most which you ignore, then again ignore my comments on you ignoring them] have ever said Kerr ring Singularities do not spin. Perhaps the question that should be put to the professors, is "Is it correct to say kerr singularities do not spin" Because in essence, among your myriad of other errors and misrepresentations about BHs. that is what you are claiming. And while no professor and no link has ever said kerr singularities do not spin, most suggest that it is a reasonable assumption, [which like other pertiment comments you ignore] to make. again the following: "I think that to say that "the Kerr's ring singularity is spinning" is a fairly reasonable intuitive interpretation of the Kerr geometry. Kerr geometry has angular momentum, and it is reasonable (at least in some respects) to think of the ring singularity as the source of this angular momentum; and for this reason it is reasonable to interpret the situation as if the ring singularity is rotating. Best regards, Amos Ori http://www-conf.slac.stanford.edu/einstein/talks/kip-bhs.pdf "I don't know what it means to say that the "singularity spins" or not. The Kerr solution certainly has angular momentum---a notion that is well defined at infinity---and it would probably not be unreasonable to view the ring singularity as "producing" this angular momentum". Robert Wald: No Professor has ever said "A SINGULARITY DOES NOT SPIN" And I suggest to you, that if all the professors were to be "privileged" to all your comments re BHs here and the other BH thread, your silly sanctimonious pretentious attitude as shown above, they would be aghast with disbelief. Let me again inform you, no forum member has supported your concept, and no professor or link has ever suggested that the Kerr Singularity does not spin. Those are facts.
