Acceleration of particles to high energy via gravitational repulsion in the Schwarzschild field
Published 14 Feb 2018 in astro-ph.HE and gr-qc | (1802.08546v1)
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.
