In this paper, therefore, we explore the possibility that the universe is slightly open with Ω0 ≈ . In this case a glimpse of preinflation fluctuations could just now be entering the horizon before the universe becomes totally dark-energy dominated and flat. Our goal, therefore, is to determine what constraints might be placed on inhomogeneities and curvature content in the preinflation universe based upon current cosmological observations. |
