Total Energy of the Bianchi Type I Universes
Abstract
Description
Using the symmetric energy-momentum complexes of Landau and Lifshitz, Papapetrou, and Weinberg we obtain the energy of the universe in anisotropic Bianchi type I cosmological models . The energy (due to matter plus field) is found to be zero and this agrees with a previous result of Banerjee and Sen who investigated this problem using the Einstein energy-momentum complex. Our result supports the importance of the energy-momentum complexes and contradicts the prevailing ``folklore'' that different energy-momentum complexes could give different and hence unacceptable energy distribution in a given space-time. The result that the total energy of the universe in these models is zero supports the viewpoint of Tryon. Rosen computed the total energy of the closed homogeneous isotropic universe and found that to be zero, which agrees with the studies of Tryon.
