A Solution to the Cosmological Constant Problem
The fluctuations of the vacuum energy are treated as a non-equilibrium process and a stochastic model for the cosmological constant is presented, which yields a natural explanation for the smallness or zero value of the constant in the present epoch and its large value in an era of inflation in the early universe. Typeset using REVTEX 1 It is widely considered that the problem of the cosmologic...
متن کاملA Solution to the Cosmological Constant Problem
The status of the cosmological constant Λ has long been discussed, whereas it is clearly established in General Relativity (GR) as universal constant. Therefore, similarly to Newton constant of gravitation G, its value has to be estimated from observations. However, such an estimate does not agree by hundred orders of magnitude with its expected value as obtained from quantum field theories by ...
متن کاملCosmic acceleration as the solution to the cosmological constant problem∗
In this paper we provide both a diagnosis and resolution of the cosmological constant problem, one in which a large (as opposed to a small) cosmological constant Λ can be made compatible with observation. We trace the origin of the cosmological constant problem to the assumption that the local gravitational Newton constant G (as measured in a Cavendish experiment) sets the scale for global cosm...
متن کاملCosmic Acceleration as the Solution to the Cosmological Constant Problem * I. Diagnosis of the Cosmological Constant Problem
In this paper we provide both a diagnosis and resolution of the cosmo-logical constant problem, one in which a large (as opposed to a small) cos-mological constant Λ can be made compatible with observation. We trace the origin of the cosmological constant problem to the assumption that the local gravitational Newton constant G (as measured in a Cavendish experiment) sets the scale for global co...
متن کاملLagrangian Formulation of a Solution to the Cosmological Constant Problem
A covariant Lagrangian formulation of a solution to the cosmological constant problem, based on vizualising the fluctuations of the vacuum energy as a nonequilibrium process with stochastic behaviour, is presented. The variational principle yields equations of motion for the cosmological “constant” Λ, treated as a dynamical field, together with an equation for a Lagrange multiplier field φ, and...
