Here's a thought.
Lets assume that gravity is a geometry, and the carrier of this information is the graviton.
Now liken this geometry to a ruler. When you move the ruler, every point of the ruler will see the move instantaneously unlike a photon which would have to travel the moved distance.
Now, current thinking implies that empty space is not empty but full of dark energy, so perhaps the graviton is part of this dark energy and this dark energy forms the gravitational geometry.
Just a thought, use it or lose it
