The case for a four dimensional graviton mass (non zero) influencing reacceleration of the universe in five dimensions is stated, with particular emphasis upon if five dimensional geometries as given below give us new physical insight as to cosmological evolution. One noticeable datum, that a calculated inflaton φ (t) may partly re-emerge after fading out in the aftermath of inflation. The inflaton may be a contributing factor to, with non zero graviton mass, in re acceleration of the universe a billion years ago. Many theorists assume that the inflaton is the source of entropy. The inflaton also may be the source of re acceleration of the universe, especially if the effects of a re emergent inflaton are in tandem with the appearance of macro effects of a small graviton mass, leading to a speed up of the rate of expansion of the universe one billion years ago, at red shift value of Z ~ .423. The key formula, for joint DM-DE shows up in terms of deceleration parameter, Q(z). The choice of the DM-DE eqn. may eventually illuminate how early BBN may affect the formation of low levels of lithium for early star formation which we reference toward the end of this document. We also discuss what is necessary for not only proper BBN, but also to the implications for 'atoms' of space time congruent with relic GW production, i.e. the thermodynamics of emergent structure.
