Dear Peter,
Nice to hear from you. To answer your questions:
Have you looked closely at Active Galactic Nuclei and quasar dynamics?
I assume you are talking about black hole jets and accretion discs and so forth. The black hole I came up with is basic. The main point is that inside the event horizon there is no space. The matter that is normally thought to collapse into a singularity has instead been forced into a dense shell around the event horizon by the growing "bubble of nothing" that expanded from the inside. A spinning shell would be like a flywheel and at the poles, where the rotation slows, jet outflows from accretion discs are possible.
What conclusions would your model suggest regarding the effect of what we designate dark matter?
The gravitons I came up with are also dark matter particles, although they contain no matter. Instead they impart curvature to space and so act like matter in causing gravitation. They position themselves between particles - they never interact with particles. If you were trying to detect one it would elude whatever method of detection you had, not to mention that it is essentially composed of nothing in the first place. Dark matter is thought to exist in a halo extending well beyond a galaxy. If you consider that galaxies were much closer together in the early universe, two neighboring galaxies would have had a number of gravitons between them in addition to inside them. As they drifted apart the gravitons between them followed one or the other galaxy in a halo.
I read your well illustrated essay and found it interesting that you would use a classical spin because I do the same thing with the spin-2 graviton which returns to its original state after a rotation of 180 degrees. I get how you bring a 1/2 spin particle back to its original state after a 720 degree rotation - that's good. I think the major roadblock to the acceptance of such an interpretation is that particles are thought of as points by the mainstream, where spin can only be described in terms of the abstract mathematics of linear algebra. However, particles such as an electron may have internal structure which could permit a classical spin but that is yet to be discovered. Gerald Gabrielse, a physicist at Harvard, thinks the electron may have an internal structure.
Regards,
Peter
