“…If we make the substitution of First of all, this non zero initial value of the entropy is consistent with a quantum bounce, as can be postulated through LQG, as by [5] [7] but it says more than that. In reality the very small value for the Curvature-measure k  in the aftermath of the quantum bounce, with 2 110…”

This document will from first principles delineate the degree of flatness, or deviations from, in early universe models. We will, afterwards, make comparison with recent results we have looked at concerning metric tensor fluctuations and comment upon the role of what early universe gravitational energy may play a role in the presumed deviation from flat space results. Note that ( ) 37 initial gravitoñ~1 0 N S will be tied into the presumed results for initial state density, in ways we will comment upon, leading to observations which are supporting the physics given by Equation (26) of this document as with regards to Gravitational waves, from relic conditions. The deviations from flat space may help confirm the conclusions given by Buchert, Carfora, Kolb, and Wiltshire allegedly refuting the claim by Green and Wald that "the standard FLRW model approximates our Universe extremely well on all scales, except close to strong field astrophysical objects", as well as give additional analysis appropriate for adding detail to expanding experimental procedures for investigating non FLRW models such as the Polynomial Inflation models as given by Kobayashi, and Seto, as well as other nonstandard cosmologies, as brought up by Corda, and other researchers. As well as improve upon post Bicep 2 measurements which will avoid GW signatures from interstellar dust, as opposed to relic GW. We hope that our approach may help in the differentiation between different cosmology models. Most importantly, our procedure may help, with refinement of admissible frequency range, avoid the problem of BICEP 2, which had its presumed GW signals from presumed relic conditions identical to dust induced frequencies, as so identified by the Planck collaboration in reference [25] which we comment upon in the conclusion.

“…Keep in mind we are also using the Non-Linear Electrodynamics non-zero singularity which is also a nonzero bounce for the start of the universe [30] [31]. Having said that, such effects do seem to tie in also with work the author has done in [32] which is in its own way a partial confirmation of [29] as a starting point. We will use this while assuming in our calculations H r does not go to zero.…”

We initially look at a nonsingular universe representation of entropy, based in part on what is brought up by Muller and Lousto. This is a gateway to bring up information and computational steps (as defined by Seth Lloyd) as to what will be available initially due to a modified Zero Point Energy formalism. The Zero Point Energy formalism is modified as due to Vissers's setting of an angular plane number in early universe cosmology as k(maximum) ~ 1/(Planck length), with a specific initial density giving rise to initial information content which may permit fixing the initial Planck's constant, h, which is pivotal to the setting of physical law. This will be in the spirit of Stoica's removal of initial conditions of non-pathological initial starting points in Cosmology. What we want are necessary and sufficient conditions so (today) = (initial). We also in addition make A. Beckwith 169 a brief survey into 5 th force arguments in gravity which also has a strict entropy interpretation. i.e., how to link gravity, quantum mechanics, and E and M through entropy production.
