Gedankenexperiment for Using Boltzmann Equation for Relic Graviton Density , in Pre-Planckian Physics Conditions if there Exists a Regime of Comparatively Low Temperatures (Cold Cosmologies)

Authors: Andrew Beckwith

We look at what may occur if Boltzmann equations, as presented by Muramaya in 2007, Les Houches, are applied to graviton density in a pre Planckian universe setting. Two restrictions are in order. First of all, we are assuming a graviton mass on the order of 10^-62 grams, as if the pre Planckian regime does not change the nature of Graviton mass, in its low end.. Secondly, we are also assuming that a comparatively low temperature regime (far below the Planckian temperature) exist . Secondly we are leaving unsaid what may happen if Gravitational waves enter the Planck regime of ultra high temperature. With those two considerations, we proceed to examine a Graviton density value resulting from perturbation from low to higher temperatures. Either cyclic conformal cosmology as ventured by Penrose may be the genesis of a low temperature regime, or a multiverse.
