Dark matter, dark energy and gravitational proprieties of antimatter

TL;DR

This paper proposes that gravitational repulsion between matter and antimatter could explain dark matter and dark energy phenomena, suggesting they are effects of vacuum interactions rather than new substances.

Contribution

It introduces a simple model linking gravitational polarization of the vacuum to dark matter and energy, offering a unified explanation involving known physics.

Findings

Gravitational dipoles in vacuum may mimic dark matter effects.

Vacuum energy interactions could resolve the cosmological constant problem.

Dark energy may be an emergent effect of vacuum-baryonic matter interactions.

Abstract

We suggest that the eventual gravitational repulsion between matter and antimatter may be a key for understanding of the nature of dark matter and dark energy. If there is gravitational repulsion, virtual particle-antiparticle pairs in the vacuum, may be considered as gravitational dipoles. We use a simple toy model to reveal a first indication that the gravitational polarization of such a vacuum, caused by baryonic matter in a Galaxy, may produce the same effect as supposed existence of dark matter. In addition, we argue that cancellation of gravitational charges in virtual particle-antiparticle pairs, may be a basis for a solution of the cosmological constant problem and identification of dark energy with vacuum energy. Hence, it may be that dark matter and dark energy are not new, unknown forms of matter-energy but an effect of complex interaction between quantum vacuum and known baryonic matter.
