Spacetime Fluctuations and the Cosmological Constant Problem
Spacetime geometry is treated as a fluctuating, stochastic quantum system allowing an effective quantum gravity solution to the cosmological constant problem. A Fokker-Planck equation for the probability density of spacetime metric fluctuations is solved for an FRW universe and the most probable value for the metric scale factor R is for a very small cosmological constant. e-mail: [email protected]...
متن کاملSpacetime Substantivalism and Einstein’s Cosmological Constant∗
I offer a novel argument for spacetime substantivalism: we should take the spacetime of general relativity to be a substance because of its active role in gravitational causation. As a clear example of this causal behavior I offer the cosmological constant, a term in the most general form of the Einstein field equations which causes free-floating objects to accelerate apart. This acceleration c...
متن کاملSpacetime Foam and the Cosmological Constant
In the saddle point approximation, the Euclidean path integral for quantum gravity closely resembles a thermodynamic partition function, with the cosmological constant Λ playing the role of temperature and the “density of topologies” acting as an effective density of states. For Λ < 0, the density of topologies grows superexponentially, and the sum over topologies diverges. In thermodynamics, s...

متن کاملCosmological Constant in de-Sitter Spacetime
With the basic cosmological relations that agree with the recent observations, simple expressions are suggested concerning the value of cosmological constant(Λ). A large contribution of quantum vacuum to the energy momentum tensor does not agree with the observed cosmos. However,one requires the presence of positive Λ to make the various observations consistent. After a review of the effect of ...
