Gravity leakage should create minor deviations in the motion of planets and moons. Astronauts on the Apollo 11 mission installed mirrors on the lunar surface. By shooting lasers at the mirrors, a reflected beam can be monitored from Earth to measure tiny orbital fluctuations. Dvali said deviations in the Moon's path around Earth might reveal whether gravity is really leaking away.

Interesting theory. I would like an experiment of very accurate measurements of the Earth's gravitational field at different points in its solar orbit. Unfortunately, the hypothosis behind the experiment dictates that those measurements cannot be made on Earth or near Earth, making execution just a bit of a challenge.

I bet you would find variations on the order of 10E-13 at different orbital positions.

Interesting idea. We once tried after many drinks to try to hit the Apollo mirrors with a laser (yes more powerful than a pointer). The results of the test are in dispute since we passed out before verification. Damn tequila. I still think we hit it and got a return.
