So far I don't exactly understand how Gia's picture works. But definitely, it's one of the proposals to modify gravity in the extreme infrared - he talks about the Yukawa-Newton potential (arising from massive gravity). Dvali predicts new modifications of the motion of the Moon and the planets. In the case of the Moon, it should be testable because of the mirrors on the lunar surface that have been installed by Apollo 11 (and terrestrial lasers).
I am now looking at several papers such as
Find the first gravitational wave
Incidentally, did you consider the possibility that you would be the first person in the world to discover the gravitational waves, in co-operation with the LIGO experiment? It's easy as long as you have
