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

Authors: Andrew Beckwith

In this paper Beckwith asks if DM and gravitons 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 Beckwith 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 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 dark matter ram jet. The consequences are from assuming that axions are CDM, and KK gravitons are for WDM, then up to a point, the density of warm dark matter candidates would dominate not only structure formation in early universe formation , but would also influence the viability of the DM ram jet applications for interstellar travel
