A Falsifiable Dark Energy Model: Holographic Dark Information Energy    [PDF]

Michael Paul Gough
Several models have been proposed to explain the dark energy that is causing universe expansion to accelerate. Here the acceleration predicted by the Holographic Dark Information Energy (HDIE) model is compared to the acceleration that would be produced by a cosmological constant. While identical to a cosmological constant at low redshifts, z<1, the HDIE model results in smaller Hubble parameter values at higher redshifts, z>1, reaching a maximum difference of 2.6\pm0.5% around z \sim 1.7. The next generation of dark energy measurements, both those scheduled to be made in space (ESA's Euclid and NASA's WFIRST missions) and those to be made on the ground (BigBOSS, LSST and Dark Energy Survey), should be capable of determining whether such a difference signature exists or not. The HDIE model is therefore falsifiable.
