Imagine that we go to the moon, and tie one end of a rope to the surface of the moon, and then take the other end of the rope back to earth. We cant tie it down of course, becuase it would snap as the moon moves away. So instead we make the rope long enough to be a few feet off the ground, and let it go. What happens next? Since the gravity of Earth is stronger, I assume the rope would just dangle above the ground, although moving across the sky as the moon drags it along. The foundation on the moon might have to be very strong to hold the rope, becuase the moon is pulling one way, and Earth the other.
