Experiments supporting Newton's gravitational theory

  1. Nov 8, 2011 #1
    Apart from Cavendish two lead attracting spheres experiment are there any other experiments (done in lab scale) that support Newton's gravitational theory?
    Dose scanning prop instruments (AFM, STM) suffers from drift due to gravitational attractions between the instrument mass (not the tip mass, which is very small) and large buildings around?

    Many experiments, but not scanning microscopy. Eric Adelberger's group at Washington has some of the best measurements on small scales. Large scales have tower experiments and larger still you have Venus radar ranging.

    Thanks Vanadium 50.
    Very intersting
