Energy-Momentum in the Viscous Kasner-type Universe in Teleparallel Gravity | | Mustafa Salti
; | | Date: |
4 Aug 2005 | | Journal: | Astrophys.Space Sci. 299 (2005) 159-166 | | Subject: | gr-qc | | Abstract: | Using the teleparallel gravity versions of the Einstein and Landau-Lifshitz’s energy and/or momentum complexes, I obtain the energy and momentum of the universe in viscous Kasner-type cosmological models. The energy and momentum components (due to matter plus field) are found to be zero and this agree with a previous work of Rosen and Johri it et al. who investigated the problem of the energy in Friedmann-Robertson-Walker universe. The result that the total energy and momentum components of the universe in these models is zero same as Bergmann-Thomson’s energy-momentum and props the viewpoint of Tryon. Rosen found that the energy of the Friedmann-Robertson-Walker space-time is zero, which agrees with the studies of Tryon. | | Source: | arXiv, gr-qc/0508018 | | Services: | Forum | Review | PDF | Favorites | |
