We obtain the energy and momentum of the Bianchi type universes using different prescriptions for the energy-momentum complexes in the framework of general relativity. The energy and momentum of the Bianchi universes are found to be zero for the parameter 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 case so special?”
