Quote by: Zeebadee  I'm not sure I know what you mean here. If both m-g-r's spin in sync, why would they also be swinging around each other? |
From the perspective of each spinning m-g-r, the other is swinging around it.

Quote by: Zeebadee This makes no sense whatsoever. Why would it start and then stop spinning? |
For example, when I spin around 1 time relative to the ground, what happens to a tree relative to me? The tree swings around me with 1 side always facing me. By your explanation, the tree must have spun around 1 time in order to do that. The same can be said for any object out in the universe, stars, planets, etc.
