To test the hypothesis that moonrock is gravitationally attracted to the moon slightly more than is earthrock one could measure the deviations of a balance scale weighing NASA-provided moonrock against an equal (earth) weight of (say) granitedust from horizontal during a lunar orbit cycle and compare this to the deviations of the balance when the scale is balanced by two equal weights of granitedust.
I remember reading somewhere that this or a similar experiment has been done and proven negative (consistant with G being the same for all matter) but can't now find the details.
Can anybody help? TIA.
