DESCRIPTION:In a quantum universe\, the wave function of the universe prov
 ides a measure on\nthe space of all classical histories of the universe. T
 his can be used to\nobtain predictions for local observations.\n\nWe discu
 ss several properties of the histories predicted by Hartle and\nHawking's 
 no-boundary wave function and show in particular this selects\ninflationar
 y universes. In matter models that have a parameter regime where the\ncond
 itions for eternal inflation are satisfied\,  the predicted amount of\ninf
 lation of our universe is large. This generates a spectrum of perturbation
 s\nwhose non-Gaussian features provide a potentially observable signature 
 of the\nquantum state.\n
