A Frequency Metrology approach to Newtonian constant G determination using a pair of extremely high Q simple pendulums in free decay

It is argued that simple pendulums exhibiting Q values in excess of 108 can be realized by using high strength fibres to suspend in vacuum a bob of less than 10-3 kg. For a 1 m long pendulum this means damping time constants of several years, long enough to allow experiments in free decay mode, maxi...
