On the gravitational energy-momentum of the Bonnor spacetime

Janusz Garecki

Abstract

In the paper we consider the energy and momentum of the Bonnor spacetime. We construct some non-local expressions from the Einstein canonical energy-momentum pseudotensor of the gravitational field which show that the gravitational energy and momentum in this spacetime are different from zero and do not vanish even outside of the material source (a stationary beam of the null dust) of this spacetime. KEY WORDS: gravitational superenergy, gravitational energy-momentum
