Could centrifugal force affect gravity?
How to explain my thoughts.
Say you have an inner cluster of bodies (yellow), and an outer group (green).
[ Invalid Attachment ]
Under classical Newtonian Physics, the velocity of the inner cluster of bodies (yellow) is unimportant, and it is only their mass that affects the gravitational pull on the outer cluster of bodies (green).
However, is it possible that the higher the velocity that the inner bodies (yellow) are spinning, the lower overall their gravitational pull would be on the outer bodies (green).
Obviously centrifugal/centripetal forces have to be in balance, so the orbital speed is dictated by the inward directed gravity. However, if the force of attraction between the inner bodies is reduced with higher velocities, then would it also be possible that the force of attraction between the inner and outer bodies would also be reduced?
I suppose one might also look at factors such as solar winds/cosmic rays that might in fact be asymmetrical.
(oh, and I should state that I'm not talking about spinning at the speed of light, but rather at typical galactic rotation speeds, which are pretty quick).

"Could centrifugal force affect gravity?" - Yes.

Pmb, please elaborate. Some of us will learn something.
Thanks

Since Pmb is playing coy I will give you my answer.
At the celestial velocities that you are talking about the answer is NO. However, since gravity is the result of particle charges posturing to each other there would be a theoretical fly-by velocity where the "mass" of the quark charges would prevent them from responding and posturing to each other. www.dipole.se (http://www.dipole.se)
What is that velocity ? probably penta-orders higher than celestial.

What? Since when am I playing it coy? Butchmurry asked Could centrifugal force affect gravity? and I said Yes. That's the best answer a person can give. If butchmurry wanted details and wanted me to elaborate all he had to do was to ask, and he did! So I will now get into the details the best I can.
Butchmurry - I appologize. I was careless in reading your answer so I got the wrong idea. Although my answer was correct, it was correct for the wrond reason. The inner bodies (yellow) a moving faster so they have a greater mass-energy. That energy increases the gravitational field in the region around the green bodies. The strength of the gravitational field is a function of the speed of the green bodies.
You were speaking about the centrifigul force, also referred to as the centrifigul field. The centrifugul field exists without the presence of any bodies and is a function only of the change in coordinates to rotating coordinates.
For details please see the article on this subject by Albert Einstein, the Master! :)
The article is under my web site at

Scroll down to whre you read
Albert Einstein -That the relation of gravity to inertia was the motivation for general relativity is expressed in an article Einstein wrote which appeared in the February 17, 1921 issue of Nature
Can gravitation and inertia be identical? This question leads directly to the General Theory of Relativity. Is it not possible for me to regard the earth as free from rotation, if I conceive of the centrifugal force, which acts on all bodies at rest relatively to the earth, as being a "real" gravitational field of gravitation, or part of such a field?
I referred either to this part of the web page or to this exact article by Einstein before.
Any questions on the article please let me know.
I also wrote an article on Einstein's theory of gravity before. I's at Einstein's gravitational field by Peter M. Brown, at http://xxx.lanl.gov/abs/physics/0204044
