Brans-Dicke quantum cosmology

By solving a Wheeler-De Witt 'extended' equation in the Brans-Dicke theory, we have found that the probability distribution predicts: i) An initial value for the Brans-Dicke scalar field phi similar to rho(VAC)(1/2) in the beginning of the inflation, where rho(VAC) is the vacuum density energy (this gives a planck mass similar to rho(VAC)(1/4)) ii) Large values for the Brans-Dicke parameter w. On the other hand it is shown that by taking into account the dynamical behaviour of phi and the matter scalar field sigma we can formulate a 'creation boundary condition' where in the 'beginning' of the Universe (R = O, 'nothing' for some authors) we have a dynamical sigma already 'created'. This could be the energetic mechanism which makes Universe tunnels the potential barrier to evolve classically after. Besides we have found the possibility of a cosmological uncertainty principle.
