The effects of the breaking of the scale symmetry by thermal corrections are discussed. It is argued, that the dynamical restoration of the scale symmetry at low energies and late times due to thermal corrections dragging the expectation value of the dilaton towards the origin can be avoided in realistic physical models.
Cosmological evolution of the scale invariant theory may lead to a gravitational wave signal, a discovery of which would constrain the parameter space of specific models.
