Highest-Energy Cosmic Rays and Hilbertian Repulsive Effect

TL;DR

This paper suggests that a Hilbertian repulsive effect, derived from Einstein's equations without a cosmological term, could explain a significant portion of the high energy cosmic rays from extragalactic sources.

Contribution

It introduces a novel explanation for high-energy cosmic rays based on a Hilbertian repulsive effect from Einstein's equations without cosmological constant.

Findings

Hilbertian repulsive effect can account for high-energy cosmic rays

High-energy cosmic rays may originate from extragalactic sources due to this effect

Provides a new perspective on cosmic ray origins without dark matter or dark energy assumptions

Abstract

We point out that an important portion of the high energy of the cosmic rays from extragalactic sources can be attributed to a Hilbertian repulsive effect, which is a consequence of Einstein equations without cosmological term.
