:Rob, I posted on your talk page that the rate of expansion is very small, considering the distances involved. Two objects that are relatively strongly bound gravitationally don't experience the expansion because gravity resists the very small force driving them apart. However, between two objects far enough away for gravity to be very weak, the expansion is more noticeable.
