Cosmic de Celebration Parameter Q(Z) Dependence Upon Gravitons? Implications for the DM Rocket/ram Jet Model

Authors: Andrew Beckwith

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. Another issue to consider, is if or not gravitons with mass affect DM profiles, but could also impact the cosmic acceleration of the universe, leading to an increase of acceleration one billion years ago, in a manner usually attributed to DE. Following Marcio E. S. Alves, Oswaldo D. Miranda, Jose C. N. de Araujo, 2009 in an article brought to the attention to the author by Christian Corda, the author, using his modification of Friedman equations, incorporating some brane models to allow for additional dimensions found that there is, for low graviton mass of the order of mgraviton ~ 10-65 grams similar behavior as noted by Alves, et al. 2009. If of mgraviton ~ 10-65 also is reconcilable as to KK dark matter models, which is under investigation, the new modeling super structure could have significant impact upon the DM rocket / ram jet proposal the author, Beckwith, brought up in the AIBEP meeting in Scottsville, Arizona. The author will high light what KK style gravitons, with a slightly different mass profile could mean in terms of his DM rocket proposal brought up in both Christ Church, Dark 2009, and in different form in SPESIF, 2009. I.e. value of up to 5 TeV , as opposed to 400 GeV for DM, which may mean more convertible power for a suitably designed platform.

Comments: 15 pages. Source of information for presentations on DM , and idea of DM rocket / ram jet as will in part be presented in both SPESIF, February 2010, and AIBEP, November 2009. Discussion of material of this document not involved with DM rocket are part of general back ground material for presentation by the author in ICAAM Crete, September 2009 at gravitational physics sub session run by Dr. Corda..AIBEP talk will have DM rocket/ ram jet, but also include laser physics
