Abstract
A non-minimal coupling R(phi)2 leads to a geometrical structural chang e in the evolution of the Universe which can be interpreted in terms o f a quantum tunnelling process. The origin of the Universe admits thus two interpretations: either as a classical change of the Riemannian n ature of space-time or as a quantum process. The main consequence of t his is a non-singular Soft Big Bang. The same kind of non-minimal coup ling RF2 of the electromagnetic field with gravity induces non-conserv ation of the photon number and of the total entropy.
