	Actually I hadn't thought about this a great deal before this. 
I think that the angular momentum makes the center of the solar system
(Start over) The angular momentum of the solar system makes the Sun the
at the origin the prefered coordinate system. As for the local supercluster,
the way I always understood it was that the Hubble expansion does affect it
but that there is also a strong effect due to gravitational fields 
generated by the cluster itself. I'll have to look into this somemore
at a later date.
	And thank you for posting my post.
