TL;DR
This paper introduces 'pilgrim dark energy', a holographic dark energy model where phantom-like energy prevents black hole formation, and tests its cosmological viability using recent observational data.
Contribution
It proposes a novel dark energy model based on the idea that phantom energy can inhibit black hole formation, and evaluates its observational constraints.
Findings
Pilgrim dark energy can fit observational data.
The model suggests a strong repulsive force from phantom energy.
Potential to explain cosmic acceleration without black hole formation.
Abstract
In the present work, we reconsider the idea of holographic dark energy. One of its key points is the formation of the black hole. And then, we propose the so-called "pilgrim dark energy" based on the speculation that the repulsive force contributed by the phantom-like dark energy () is strong enough to prevent the formation of the black hole. We also consider the cosmological constraints on pilgrim dark energy by using the latest observational data. Of course, one can instead regard pilgrim dark energy as a purely phenomenological model without any physical motivation. We also briefly discuss this issue.
