Loop theory, on the other hand, has grown more from the community of the relativists, the specialists of general relativity. This is a community, clearly, far more aware of the specific physical meaning of general relativity, and less impressed, on the other hand, by the techniques of quantum field theory. For a relativist, therefore, quantum gravity is more about incorporating quantum field theory into the conceptual revolution of general relativity, than in taming general relativity into conventional quantum field theory.
