Age Problem in the Holographic Dark Energy Model

TL;DR

This paper tests the holographic dark energy model against old high redshift objects and finds it incompatible unless the Hubble constant is lowered, challenging its viability.

Contribution

It provides a critical test of the original holographic dark energy model using observational data from ancient objects.

Findings

The model is incompatible with observations unless Hubble constant is reduced.

Original holographic dark energy model is ruled out under standard Hubble constant values.

The universe's age constraints challenge the model's validity.

Abstract

In this note, we test the original holographic dark energy model with some old high redshift objects. The main idea is very simple: the universe cannot be younger than its constituents. We find that the original holographic dark energy model can be ruled out, unless a lower Hubble constant is taken.
