At http://asterisk.apod.com/viewtopic.php?f=9&t=25290 I had asked about spinning, and Chris L Peterson replied, closing with "Everything is spinning. In some cases you have groups of things that are held together by other forces, and that prevents them from spinning independently of each other, that's all. Nebulas are spinning as well, although generally too slowly to notice many effects caused by it. Inside a nebula, you have all sorts of turbulent motion and spinning- it is precisely the spinning of local regions that results in the formation of stars."
Well, "turbulent motion" is not spinning; and with all those stars and density, the M13 cluster does not show spinning as a galaxy does, if a galaxy is spinning, as all do not seem to do as some do. Spin is still a mystery to me, and seems absurd in the case of spin rates into hundreds per second. I still don't think that spin is explained by talk about angular momentum, I think it could be a separate form of energy, deserving to be studied more. For instance, is being flat a result or a cause of galaxy rotation, and how do globular clusters show that.
