A Godel-Friedmann cosmology? art. no. 083506

Based on the mathematical similarity between the Friedmann open metric and Godel's metric in the case of nearby distances, we investigate a new scenar io for the universe's evolution, where the present Friedmann universe origi nates from a primordial Godel universe by a phase transition during which t he cosmological constant vanishes. Using Hubble's constant and the present matter density as input, we show that the radius and density of the primord ial Godel universe are close, in order of magnitude, to the present values, and that the time of expansion coincides with the age of the universe in t he standard Friedmann model. In addition, the conservation of angular momen tum provides, in this context, a possible origin for the rotation of galaxi es, leading To a relation between the masses and spins corroborated by obse rvational data.
