Experiments supporting Newton's gravitational theory

Click For Summary
SUMMARY

Experiments supporting Newton's gravitational theory include the Cavendish experiment and recent measurements by Eric Adelberger's group at the University of Washington, which focus on small-scale gravitational interactions. The discussion highlights that scanning probe instruments, such as Atomic Force Microscopes (AFM) and Scanning Tunneling Microscopes (STM), may experience drift due to gravitational attractions from large structures nearby. Additionally, larger-scale experiments include tower experiments and Venus radar ranging, which further validate gravitational principles.

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 interesting
