Cavendish’s 1798 torsion-balance measurements detected gravitational attraction between laboratory masses and determined the mean density of Earth.
The experiment supplied a terrestrial quantitative test of universal Newtonian gravitation; the modern value of is inferred when the result is expressed in later notation.

This is an authored directed relation from the source endpoint to the target endpoint.
The measured attraction between laboratory masses quantitatively supported universal Newtonian gravitation and permitted later extraction of .
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
