## Non Standard DE & DM, With Deceleration Parameter Q(z) In Five Dimensions

**Authors:** Andrew Beckwith

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. We postulate that a calculated inflaton φ(t) may 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
