Wave function of the inflationary universe

摘要: If one is interested in cosmological models with inflation occurring at or near the Planck energy then effects of quantum gravity have to be taken into account. We may still hope use an approximation Einstein action as a starting point but semiclassical approach breaks down, forcing us superspace construction for wave function Universe. Using recently proposed formulation ground state Universe, we obtain unique cosmology given inflationary model. Besides recovering picture, has other consequences, such following: (1) The suppressed small values scale factor and can therefore interpreted corresponding nucleation bubble universe. (2) parameters become uncorrelated which means that concept time down. (3) later times possesses structure on scales smaller than leads spacetime-foam picture view existence Universe itself consequence inflation.
