I don't see it as a contraction of space. If you place 2 equal mass objects in space with no motion (and no other external forces) then when released they will move through the space between them until they collide.

On the other hand gravity seems to be able to resist the expansion of space. The universe is expanding, distant galaxies are receding due to the expansion of space. But locally, in our solar system/galaxy/local group, we don't see this effect, gravity is holding it all together. Now that makes my brain hurt.
