Energy and Momentum of Bianchi Type VIh Universes

We obtain the energy and momentum of the Bianchi type VIh universes using different prescriptions for the energy-momentum complexes in the framework of general relativity. The energy and momentum of the Bianchi VIh universes are found to be zero for the parameter h=-1 of the metric. The vanishing of these results supports the conjecture of Tryon that the universe must have a zero net value for all conserved quantities. This also supports the work of Nathan Rosen with the Robertson-Walker metric. Moreover, it raises an interesting question: “Why is the h=-1 case so special?”
