Dark Energy Present and Future

  title={Dark Energy Present and Future},
  author={Paul H. Frampton},
By studying the present cosmological data, particularly on CMB, SNeIA and LSS, we find that the future fate of the universe, for simple linear models of the dark energy equation‐of‐state, can vary between the extremes of (I) a divergence of the scale factor in as little as 7 Gyr; (II) an infinite lifetime of the universe with dark energy dominant for all future time; (III) a disappearing dark energy where the universe asymptotes as t → ∞ to a(t) ∼ t2/3 i.e. matter domination.
