Hi Peter,
Thanks for asking, I'm doing ok for the time being, I just have to stay out of the heat with my MS, so my boating and fishing is done at night.
Peter, I have a link to a site that you should read regarding the association of Black holes and the rotation speed of galaxies,especially the speed of stars at the rim,

As far as the asteroid belt origins, I have read that there is not enough mass in the asteroid belt, for it to have been a planet which may have been destroyed in the past, strangely enough I find its location a bit intriguing.
I can't help but thinking of the origins of our Moon, and how this may be tied into the origin of our asteroid belt.
From what I understand there were many more bodies orbiting our Sun when it was first formed than the planets we see today, these objects were of all different sizes, some were flung into the sun, some were sent out of the system, while others were simply absorbed via impacts (accretion) with the current existing planets.
In my mind there is something missing with this theory, its the Orbital motion of our star in our own galaxy, that concerns me, its the Z axis oscillation (the crossing of our sun back and forth through a galactic arms) and our spring like movement up and down through the dense galactic plane.
such motion, in my mind, could be responsible for not only the creation of our star Sol, by gravitationally collapsing the gas cloud that made up our sun, but it could also be the engine for the Orpheus oblique impact theory that may have created our Moon, plus several mass extinction events.
I don't understand why the asteroid belt which lies between Mars and Jupiter couldn't have been a very small dwarf planet before an impact event, triggered by our orbital motion around our galaxy, causing gravitational perturbations and interactions with other unseen objects in our path as we orbited our galaxy, or debris from an unknown encounter while we orbited our galaxy.
This to me would explain not only the asteroid belt but also the Kuiper belt objects. it seems a little weird that objects were able to condense into dwarf planets in the kuiper belt but not in our asteroid belt.
It would seem to me that either the kuiper belt objects were captured or were formed by the unknown gravitational effects that we may have encountered by other objects in our path around the galaxy.
after I learned of our suns motion around our galaxy, it just occurred to my untrained mind that this could explain a lot of things.
