Acceleration of particles to high energy via gravitational repulsion in the Schwarzschild field

TL;DR

This paper explores how gravitational repulsion in the Schwarzschild solution of general relativity can be harnessed to accelerate particles to extremely high energies, potentially explaining the origins of cosmic rays.

Contribution

It demonstrates that gravitational repulsion in Schwarzschild spacetime can be used to accelerate particles to cosmic ray energies, offering a new perspective on high-energy astrophysical processes.

Findings

Gravitational repulsion exists in Schwarzschild spacetime.

Particles can be accelerated to high energies via gravitational effects.

This mechanism could explain the origin of cosmic rays.

Abstract

Gravitational repulsion is an inherent aspect of the Schwarzschild solution of the Einstein-Hilbert field equations of general relativity. We show that this circumstance means that it is possible to gravitationally accelerate particles to the highest cosmic ray energies.
