Abstract

The 2013 cosmology results from the European Space Agency Planck spacecraft provide new limits to the dark energy equation of state parameter. Here we show that Holographic Dark Information Energy (HDIE), a dynamic dark energy model, achieves an optimal fit to the published datasets where Planck data is combined with other astrophysical measurements. HDIE uses Landauer's principle to account for dark energy by the energy equivalent of information, or entropy, of stellar heated gas and dust. Combining Landauer's principle with the Holographic principle yields an equation of state parameter determined solely by star formation history, effectively solving the 'cosmic coincidence problem'. While HDIE mimics a cosmological constant at low red-shifts, z<1, the small difference from a cosmological constant expected at higher red-shifts will only be resolved by the next generation of dark energy instrumentation. The HDIE model is shown to provide a viable alternative to the main cosmological constant/vacuum energy and scalar field/quintessence explanations.

Highlights

  • Measurements of type 1a supernovae [1,2] show that a dark energy of unknown origin has caused an acceleration of the universe expansion in recent times

  • We show the Holographic Dark Information Energy (HDIE) model [12,13] provides a reasonable account of dark energy and can solve the cosmic coincidence problem, just by taking a simple phenomenological approach

  • The Holographic principle [26,27,28] asserts that the number of degrees of freedom in any region of space is proportional to the area of its boundary, rather than to its volume

Summary

Introduction

Measurements of type 1a supernovae [1,2] show that a dark energy of unknown origin has caused an acceleration of the universe expansion in recent times. We show the Holographic Dark Information Energy (HDIE) model [12,13] provides a reasonable account of dark energy and can solve the cosmic coincidence problem, just by taking a simple phenomenological approach This approach contrasts with previous, more theoretical, holographic dark energy explanations [14,15,16]. HDIE proposes that dark energy is the energy equivalent of information, or entropy, associated with stellar heated gas and dust This present work shows that the HDIE model provides a good fit to the dark energy values derived from the recently released results of the Planck mission [17] and compares favourably with the two main dark energy theories
