I must say that the vast majority of research in the field of gravity associated with the repetition of the Cavendish experiment. Let me remind you what it's essence: two balls of small mass on a rigid strut L form stable filaments on a trapeze. Balanced trapeze is very sensitive to the lateral force - resistance to twisting the threads are very few. If one of the balls present a large ball (mass M), the angle of twist can be seen on the acting force of attraction of bodies. The masses and distances are known.
