A Model for Early Universe Entropy (EUS) resulting in New Dark Matter Candidates

A model is proposed for the physics of spacetime for the time frame of the Slow Roll Inflation Approximation (SRA)¹, This model assumes the validity of the SRA and develops a mechanism involving Entropy to generate inflation. Main results include:

1. a calculation of the entropy for space time² that decreases as one moves back in time towards the big bang (BB),

2. a spectrum of resulting dark matter massive particles (entropons), and

3. an underlying inflation mechanism for dark matter 3-forms³ from the RR sector of the GSO projection⁴ in string theory that populate this spacetime along with the gravitons and gravitinos of that sector.

Insights from the work of Howard Morowitz⁵ provided motivation to develop EUS. EUS calculates the entropy of spacetime by quantizing spacetime with increasing symmetry as one looks further back in time. An explanation for the BB is also apparent in the model. Unfortunately the masses of the predicted dark matter particles are not likely to be observable in the current universe but their eventual distribution in relation to ordinary matter involving halos can be implied. The calculations that have been done for this model will be summarized. Further pathways of applying the model will be suggested.
