Phantom Dark Energy and its Cosmological Consequences

TL;DR

This paper explores phantom dark energy, which violates the null energy condition and is supported by current supernova data, examining its classical and quantum cosmological implications and introducing the concept of phantom duality.

Contribution

It introduces the concept of phantom duality and analyzes classical and quantum models with phantom energy as a matter source.

Findings

Phantom energy violates the null energy condition.

Current supernova data supports the existence of phantom dark energy.

The paper discusses the phenomenon of phantom duality.

Abstract

I discuss the dark energy characterized by the violation of the null energy condition ($\varrho + p \geq 0$), dubbed phantom. Amazingly, it is admitted by the current astronomical data from supernovae. We discuss both classical and quantum cosmological models with phantom as a source of matter and present the phenomenon called phantom duality.
