Visual science, (G)ravitational constant (6/40) Mass is inextricably linked to gravity, so that all objects no matter how tiny have a proportional gravitational pull on each other. A team of researchers measured the smallest gravitational pull so far, it was equivalent to around the mass of a ladybug. There setup had no more “give” downward but it can freely spin horizontally, they did this by placing a larger weight next to those small one's on the ends of the beam, the two weights will attract each other and turn the rod ever so slightly and this force of gravity can be measured.
