Abstract

The quantization of gravity, and its unification with the other interactions, is one of the greatest challenges of theoretical physics. Current ideas suggest that the value of G might be related to the other fundamental constants of physics, and that gravity might be richer than the standard Newton-Einstein description. This gives added significance to measurements of G and to Cavendish-type experiments.
