Cavendish experiment - Wikipedia Instead, the result was originally expressed as the relative density of Earth, [5] or equivalently the mass of Earth His experiment gave the first accurate values for these geophysical constants The experiment was devised sometime before 1783 by the English geologist John Michell, [6][7] who constructed a torsion balance apparatus for it
