Tryon’s Conjecture and Energy and Momentum of Bianchi Type Universes

الملخص EN

The energy and momentum of some diagonal anisotropic Bianchi type Universes are obtained using different energy-momentum complexes in the framework of General Relativity.

The Møller energy is found to be zero for all the Universes considered in the present work.

In all other prescriptions, the energy and momentum vanish when the sum of the metric parameters α and β vanishes.

This result obviously raises a question: why this specific choice? We have explored Tryon’s conjecture that the Universe must have a zero net value for all conserved quantities to get some ideas on this issue.
