Abstract

The Weyl theory of gravity is asymptotically free; for energies below the Planck scale, the coupling becomes strong. We suggest that the elementary vierbein fields then form a massless spin 2 bound state, whose low energy effective action is Einstein theory. This is analogous to the emergence of an effective theory of pions from QCD.
