On the origin of the holographic universe

TL;DR

This paper critically reexamines the holographic dark energy concept, showing it cannot be easily mimicked and providing precise bounds based on entropy considerations and electron magnetic moment experiments.

Contribution

It offers a more precise analysis of holographic dark energy limits using entropy bounds and experimental data, challenging previous claims of its mimickability.

Findings

Holographic dark energy cannot be easily mimicked as previously claimed.

Entropy bounds from lattice field theory and black hole thermodynamics are crucial.

Electron $(g-2)$ experiments constrain corrections to magnetic momentum to about 10^{-23}.

Abstract

In this work, we reexamine the holographic dark energy concept proposed already for cosmological applications. By considering, more precisely, the bounds on the entropy arising from lattice field theory on one side and Bekenstein-Hawking entropy of black holes on another side, it is shown that the so-called holographic dark energy cannot be mimicked as easily as claimed in the literature. In addition, the limits on the electron $(g-2)$ experiments are taken into account again. It is shown that the corrections to the electron magnetic momentum are of the order of ${\mathcal{O}}(10^{-23})$.
