In the 12th Marcel Grossmann Meeting, July 9th, 2009, the author raised the issue of whether early graviton production could affect non-Gaussian contributions to DM density profiles. Non gaussianity of evolving cosmological states is akin to asking if there is a way to get quantum contributions due to squeezed initial vacuum states which act highly non classically. If particle counting algorithms in graviton production is important as for entropy, and if entropy perturbations affects the density profile of dark matter clumping profiles, then there is room to ask to what degree initial perturbations affecting structure formation are due to classical/ non linear processes, or more quantum theoretic states. If squeezing of the initial vacuum states is essential in the relic conditions, then quantization is unavoidable. If squeezing is not essential, then coherent initial vacuum states may contribute in semi classical ways to GW production. The end result of this stated inquiry may be answering if or not gravity in the onset of inflation is a quantized field. Or if a highly non linear set of complex initial conditions for gravity can be stated using purely classical models, as T'Hooft, Corda, and others believe.
Comments: 32 pages, 3 figures [ part a and b of figure 3, which are of the same process ] (instead of four ). Re do of conclusion, plus some other changes after first version of this article rejected by American physics journal. Now sent to European physics journal. Emphasis put upon , in conclusion an open inquiry as to how to use concept of entropy as a way to add more structure to obtaining from a GW detector the normalized GW 'energy density' "function" which may have coupling of gravitons with E and M & other stuff. Open question as to if Instanton-anti instanton representation of graviton as a way to explain 10^ - 65 gram supposed deviation of graviton from usual zero rest mass in zeroth order KK tower representation of KK gravitons introduced, as possible deviation from correspondence principle. Possible role for t'Hoofts treatment of QM in his 2006 article about deterministic QM, as embedding background for QM.
