# Entropic considerations on the Universe and Universe-Black Hole Systems

## TL;DR

This paper investigates the entropic bounds of the Universe and Universe-Black Hole systems with various dark energy models, concluding that the cosmological constant uniquely satisfies these bounds among negative pressure candidates.

## Contribution

It demonstrates that entropic considerations favor the cosmological constant over other exotic dark energy fields in cosmological models.

## Key findings

- Cosmological constant satisfies entropic bounds.
- Exotic fields like quintessence and phantom are less compatible.
- Entropic criteria can distinguish viable dark energy models.

## Abstract

We study the entropic considerations on the Universe system and the Universe-Black hole system, filled by cosmological constant or exotic quintessence-like and phantom-like fields having negative pressure, using their relevant entropic bounds. It turns out that for both systems these considerations single out the cosmological constant, among the negative pressure candidate fields, as the viable cosmological field.
