An Alternative Approach to Holographic Dark Energy
We outline a scenario in which dark energy is associated with the particle horizon. An energy density related to the area of the particle horizon is found to behave in accordance with current observational constraints. The equation of state drops as the particle horizon traverses a closed universe. Depending on the constant of proportionality, either the ensuing inflationary period prevents the...
متن کاملExplaining Holographic Dark Energy
The physical origin of holographic dark energy (HDE) is investigated. The main existing explanations, namely the UV/IR connection argument of Cohen et al, Thomas’ bulk holography argument, and Ng’s spacetime foam argument, are shown to be not satisfactory. A new explanation of the HDE model is then proposed based on the ideas of Thomas and Ng. It is suggested that the dark energy might originat...
متن کاملHolographic Dark Information Energy
Landauer’s principle and the Holographic principle are used to derive the holographic information energy contribution to the Universe. Information energy density has increased with star formation until sufficient to start accelerating the expansion of the universe. The resulting reduction in the rate of star formation due to the accelerated expansion may provide a feedback that limits the infor...
متن کاملHolographic Dark Information Energy: Predicted Dark
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 parame...
متن کاملGeneralized Holographic Dark Energy Model
In this paper, the model of the holographic Chaplygin gas has been extended to two general cases: first the case of a modified variable Chaplygin gas and second the case of the viscous generalized Chaplygin gas. The dynamics of the model is expressed by the use of scalar fields and scalar potentials.
