Beyond LCDM: Bits join the Dark Side

We are encouraged to look beyond LambdaCDM as there are no satisfactory explanations for dark energy or dark matter. An evidence based approach applies two foundational principles of information theory to show dark energy and dark matter may be Holographic Dark Information Energy, HDIE. HDIE explains many effects attributed separately to Lambda and CDM. HDIE mimics Lambda with sufficient energy and an equation of state parameter, w= -1.03+-0.05 at redshifts z ~1.35, HDIE was phantom, w = -1.82+-0.08, enabling the model to be falsified. HDIE fits Planck dark energy wo-wa plots at least as well as Lambda, and is consistent with other results that suggest dark energy was phantom at earlier times. A new w-parameterisation is proposed, as the usual CPL parameterisation is unsuitable for distinguishing between HDIE/baryon and LambdaCDM models.
