Heal the world: Avoiding the cosmic doomsday in the holographic dark energy model

TL;DR

This paper proposes a modification to the holographic dark energy model using braneworld cosmology, which removes the big-rip singularity and results in a stable de Sitter universe.

Contribution

It introduces extra-dimensional effects into the holographic dark energy model to prevent cosmic doomsday scenarios.

Findings

Big-rip singularity can be avoided with extra dimensions.

The universe ends in a de Sitter phase instead of a catastrophic singularity.

The modified model remains consistent with holographic principles.

Abstract

The current observational data imply that the universe would end with a cosmic doomsday in the holographic dark energy model. However, unfortunately, the big-rip singularity will ruin the theoretical foundation of the holographic dark energy scenario. To rescue the holographic scenario of dark energy, we employ the braneworld cosmology and incorporate the extra-dimension effects into the holographic theory of dark energy. We find that such a mend could erase the big-rip singularity and leads to a de Sitter finale for the holographic cosmos. Therefore, in the holographic dark energy model, the extra-dimension recipe could heal the world.
