Gravitons Writ Large; I.e. Stability, Contributions to Early Arrow of Time, and Also Their Possible Role in re Acceleration of the Universe 1 Billion Years Ago?

Authors: A. Beckwith

This document is due to a question by Debasish of the Saha institute of India asked in the Dark Side of the Universe conference, 2010, in Leon, Mexico, and also is connected with issues as to the initial configuration of the arrow of time brought up in both Rudn 10 , in Rencontres de Blois, and Fundamental frontiers of physics 11 , in Paris, in July 2010. Further reference is made as to how to reconcile early inflation with re acceleration, partly by dimensional analysis and partly due to recounting a suggestion as by Yurov , which the author thinks has merit and which ties into, to a point with using massive gravitons as a re acceleration of the universe a billion years ago enabler, as perhaps a variant of DE.

Comments: 19 pages, one figure. Ties in DM and DE, in terms of a treatment partly suggested by Yurov, as of 'double inflation'.
