Global and local Weyl invariant theories may solve the hierarchy problem and generate all mass scales
spontaneously, initiated by a dynamical process of “inertial spontaneous symmetry breaking” that does not involve
a potential. I will discuss how viable inflation readily occurs in a scale invariant version of Starobinsky (R 2 )
inflation and how an hierarchy of mass scales may be generated, stable against Standard Model radiative
corrections. The stability against gravitational corrections is also discussed
