Anthropic Principle Favors the Holographic Dark Energy

TL;DR

This paper explores how the anthropic principle influences holographic dark energy models, showing they align better with observations than cosmological constant models, especially when the dark energy equation of state decreases over time.

Contribution

It demonstrates that holographic dark energy models are favored by the anthropic principle over cosmological constant models under certain conditions.

Findings

Holographic dark energy performs better than the cosmological constant when density fluctuation amplitude varies.

Anthropic predictions match observations more closely for dark energy with decreasing w.

Variable amplitude of density fluctuations enhances the viability of holographic dark energy models.

Abstract

We discuss the anthropic principle when applied to the holographic dark energy. We find that if the amplitude of the density fluctution is variable, the holographic dark energy fares better than the cosmological constant. More generally, the anthropic predictions agree better with observation for dark energy with $w_\d=p_\d/\rho_\d$ decreasing over time.
