Energy and Momentum of a Stationary Beam of Light
Thomas T. Bringley

TL;DR
This paper demonstrates that various energy-momentum complexes yield consistent and meaningful results for the energy and momentum of a stationary beam of light, supporting the Cooperstock hypothesis.
Contribution
It shows the equivalence of different energy-momentum complexes in calculating the energy-momentum of a stationary light beam, affirming the Cooperstock hypothesis.
Findings
All complexes give consistent results for Bonnor spacetime.
Results support the validity of the Cooperstock hypothesis.
Confirms the physical meaningfulness of energy-momentum complexes.
Abstract
The energy-momentum complexes of Einstein, Landau-Lifshitz, Papapetrou, and Weinberg give the same and meaningful results for the energy and momentum of the Bonnor spacetime describing the gravitational field of a stationary beam of light. The results support the Cooperstock hypothesis.
