What the Null Energy Condition Tells us About Gravitational Wave Frequencies in / for Relic Cosmology?

Authors: A. Beckwith

We introduce a criterion as to the range of HFGW generated by early universe conditions. The 1 to 10 Giga Hertz range is constructed initially starting with what Grupen writes as far as what to expect of GW frequencies which can be detected assuming a sensitivity of h ~ 10-27 . From there we examine the implications of an earlier Hubble parameter at the start of inflation , and a phase transition treatment of pre to post Planckian inflaton physics. We close with an analysis of how gravitational constant G may vary with time , the tie in with the NEC condition and how to select a range of relic GW frequencies.

Comments: 17 pages, one table. Attempt to start preparing for bridge to actual experimental measurements. Based upon some structural considerations as far as space time geometry.
