- No, I'm not saying that. I am saying that the Hubble recession is a
- result of initial conditions, not of repulsive interactions between
- the objects or of "dragging" by expanding space.
-
- Consequently, (as I said above) if the initial conditions are zero relative
- motion, the Hubble expansion will not create any. The subsequent motion
- of the particles is described solely by their conventional interactions
- (electrical, gravitational, etc).

- My view is in agreement with the BB, and your question has been answered.
- Space doesn't "expand" the way you suggest.
