Energy Contents of Plane Gravitational Waves in Teleparallel Gravity M. Sharif * and Sumaira Taj † Department of Mathematics, University of the Punjab, Quaid-e-Azam Campus, Lahore-54590, Pakistan. Abstract The gravitational energy-momentum and its related quantities for plane gravitational waves are evaluated in the framework of teleparal- lel theory using Hamiltonian approach. We find that energy-momentum is non-positive while the angular momentum becomes constant. This shows consistency with the results available in literature. Further, the gravitational pressure is investigated. Keywords: Teleparallel gravity; Plane gravitational waves; Energy. 1 Introduction General Relativity shows consistency with Special Relativity in different as- pects, particularly with the principle that nothing travels faster than light. Thereby the alterations in the gravitational field, i.e., gravitational waves cannot be experienced everywhere instantly as they must propagate at ex- actly the speed of light. These waves travel outwards from the source, car- rying energy and information about the astrophysics of the source. Einstein showed that accelerating masses emit gravitational waves. * msharif@math.pu.edu.pk † sumairataj@ymail.com 1
