Abstract: | We show that the conformal Weyl-Eddington theory can yield an effective long-ranged theory of gravity in accord with observations. In the framework of induced gravity, an R2 term is induced with a finite calculable coefficient with just the right sign for the theory to be free from tachyons. Our observation is not true order by order in perturbation theory. |
