%X Based on the latest Planck surveys, the universe is close to being remarkably flat, and yet, within observational error, there is still room for a slight curvature. If the curvature is positive, then this would lead to a closed universe, as well as allow for a big bounce scenario. Working within these assumptions, and using a simple model, we predict that the cosmos may have a positive curvature in the amount, <span style=\"white-space:nowrap;\"><span style=\"white-space:nowrap;\">¦¸<sub>0</sub>=1.001802</span></span>, a value within current observational bounds. For the scaling laws associated with the density parameters in Friedmann¡¯s equations, we will assume a susceptibility model for space, where, <img src=\"Edit_18751d6f-dbfa-47ba-be7c-8298073a34fd.png\" alt=\"\" style=\"white-space:normal;\" />, equals the smeared cosmic susceptibility. If we allow the <img src=\"Edit_18751d6f-dbfa-47ba-be7c-8298073a34fd.png\" alt=\"\" /> to <em>decrease with increasing</em> cosmic scale parameter, ¡°<em>a</em>¡±, then we can predict a maximum Hubble volume, with minimum CMB temperature for the voids, before contraction begins, as well as a minimum volume, with maximum CMB temperature, when expansion starts. A specific heat engine model for the cosmos is also entertained for this model of a closed universe.
