Re: [math-fun] Donald Saari on Dark Matter

Saari's analysis could have been performed by Maxwell; indeed, it essentially *was* performed by Maxwell, as Saari relies heavily on Maxwell's analysis of ring systems. Saari's work is classical Newtonian; no GR need apply. On the other hand, the equations that the "dark matter" folk have been relying on are also classical Newtonian. I wonder how much of Saari's analysis would fail in a GR setting? At 10:30 AM 7/17/2015, Paul R. Pudaite wrote:
