On the Zero-Energy Universe

“…In support of this view, we shall show that the pseudotensor theory [1] points out to a null-energy for a Robertson-Walker-flat Universe, in a Cartesian-coordinates calculation [3, 5-9, 17-20, 23, 26, 32, 34, 40]. Next, we shall show that in spherical coordinates, we would obtain a wrong result, but see also [27][28][29][30]. Recent developments include torsion models [36], and, a paper by Xulu [39].…”

“…In the following calculation, we found a counter-counter-example, where the use of spherical coordinates, although tragic earlier, does no harm in the Landau-Lifshitz calculation. We thank J. Katz, for several advises, in order to allow any kind of coordinates in energy calculations, and that superpotentials should be preferred, because our calculations would be simplified [27][28][29][30].…”
