Einstein gravitation as a long wavelength effective field theory

Abstract
A possible resolution of the difficulties in quantizing general relativity is provided by the suggestion that Einstein gravitation is not a fundamental field theory, but rather is a long-wavelength effective field theory, arising as a scale-symmetry-breaking effect in a renormalizable fundamental theory. In unified theories of this type, Newton’s constant will be calculable in terms of fundamental particle masses. The history and current status of these ideas is reviewed.
