Eternal Acceleration from M-theory

  title={Eternal Acceleration from M-theory},
  author={J. Mark Heinzle}
The dimensional reduction of D-dimensional spacetimes arising in string/M-theory, to the conformal Einstein frame, may give rise to cosmologies with accelerated expansion. Through a complete analysis of the dynamics of doubly warped product spacetimes, in terms of scale invariant variables, it is demonstrated that for D ≥ 10, eternally accelerating 4-dimensional κ = −1 Friedmann cosmologies arise from dimensional reduction on an internal space with negative Einstein geometry.
