ov 2 00 6 Wormhole with varying cosmological constant
It has been suggested that the cosmological constant is a variable dynamical quantity. A class of solution has been presented for the spherically symmetric space time describing wormholes by assuming the erstwhile cosmological constant Λ to be a space variable scalar, viz., Λ = Λ(r). It is shown that the Averaged Null Energy Condition (ANEC) violating exotic matter can be made arbitrarily small...
متن کاملVarying Fine-Structure Constant and the Cosmological Constant Problem1
We start with a brief account of the latest analysis of the Oklo phenomenon providing the still most stringent constraint on time-variability of the fine-structure constant α. Comparing this with the recent result from the measurement of distant QSO’s appears to indicate a non-uniform time-dependence, which we argue to be related to another recent finding of the accelerating universe. This view...
متن کاملPossible Cosmological Implications of a Time Varying Fine Structure Constant
Webb et al. [2] experimental results on the fine strucutre “constant ” variation with the age of the Universe, is here analized. By using the experimental data on the fine-structure “constant ”’s variation with the age of the Universe, and Dirac’s LNH (Large Number Hypothesis), we find how should vary the total number of nucleons in the Universe, the speed of light, Newton’s gravitational “cons...
متن کاملMass-Varying Neutrinos from a Variable Cosmological Constant
We consider, in a completely model-independent way, the transfer of energy between the components of the dark energy sector consisting of the cosmological constant (CC) and that of relic neutrinos. We show that such a cosmological setup may promote neutrinos to mass-varying particles, thus resembling a recently proposed scenario of Fardon, Nelson, and Weiner (FNW), but now without introducing a...
متن کاملPlanetary Perturbation with cosmological Constant
A contribution of quantum vacuum to the energy momentum tensor is inevitably experienced in the present universe. One requires the presence of non-zero cosmological constant (Λ) to make the various observations consistent. A case of Λ in the Schwarzschild de Sitter space-time shows that precession of perihelion orbit provides a sensative solar test for non-zero Λ. Application of the relations i...
