Spacetime Foam, Midisuperspace, and the Cosmological Constant
نویسندگان
چکیده
Perhaps the cosmological constant really is huge at Planck scale, but “hidden” by scale quantum fluctuations of spacetime. I briefly review this proposal and provide some evidence, coming from a simplified midisuperspace model, that an appropriate “foamy” structure can do job hiding large constant, persist under time evolution.

Spacetime 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 کاملA Spacetime Foam approach to the cosmological constant and entropy
A simple model of spacetime foam, made by N wormholes in a semiclassical approximation, is taken under examination. The Casimir-like energy of the quantum fluctuation of such a model and its probability of being realized are computed. Implications on the Bekenstein-Hawking entropy and the cosmological constant are considered.
متن کاملEntropy and the cosmological constant: a spacetime-foam approach
The problem of merging General Relativity with Quantum Field Theory is known as Quantum Gravity. One aspect of this merged theories is that at the Planck scale, spacetime could be subjected to topology and metric fluctuations[1]. Such a fluctuating spacetime is known under the name of “spacetime foam” which can be taken as a model for the quantum gravitational vacuum. At this scale of lengths (...
متن کاملSpacetime 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]...
