# Harnessing Dark Energy in Five-dimensional Brans-Dicke Universe

## TL;DR

This paper explores a five-dimensional Brans-Dicke universe where the fifth dimension acts as a source of dark energy, potentially explaining cosmic acceleration without singularities.

## Contribution

It introduces a novel dark energy model derived from the fifth dimension in Brans-Dicke theory, avoiding big rip singularities.

## Key findings

- Fifth dimension acts as a source of dark energy.
- Dark energy behaves similarly to cosmological constant.
- Model is free from big rip singularity.

## Abstract

In trying to explain the present accelerated expansion of the universe in the light of a five-dimensional Brans-Dicke theory, it is found that the fifth dimension itself here acts as a source of dark energy. It may be taken as a curvature-induced form of dark energy, in one case of which it behaves similar to that form of dark energy arising out of the cosmological constant which is the most commonly accepted form of dark energy. It is also found that this new type of dark energy is free from big rip singularity, and may be taken as a viable form of dark energy which can explain some of physical mysteries of the universe.
