Newton's gravity equation F = (G m1 m2)/r2 is verified by Cavendish using lead spheres that gravitational force is measured using a torsion mechanism which is an extremely crude and inaccurate experiment since Cavendish is measuring a force of 1 µg that is approximately equal to the weight of a single grain of pollen. In an alternative experiment, a lead sphere (2 kg) is suspended using a thin titanium wire (1.5 m), and placed at the center, of the outer surface, of a moveable 2000 kg lead block (fig 12). The angle of the wire is monitored, using two lasers beams. The lead sphere is initially situated .001 mm from the outer surface, near the center, of the lead block, then the lead block is moved away from the suspended lead sphere. After the lead block is moved 1 cm from the suspended lead sphere, there is no measurable change in the angle of the wire, that is suspending the lead sphere, which contradicts Cavendish's experiment and Newton's gravity equation.
