# Future state of the universe

@article{Dabrowski2006FutureSO, title={Future state of the universe}, author={Mariusz P. Da̧browski}, journal={Annalen der Physik}, year={2006}, volume={15} }

Following the observational evidence for cosmic acceleration which may exclude a possibility for the universe to recollapse to a second singularity, we review alternative scenarios of its future evolution. Although the de Sitter asymptotic state is still an option, some other asymptotic states which allow new types of singularities such as Big‐Rip (due to a phantom matter) and sudden future singularities are also admissible and are reviewed in detail. The reality of these singularities which…

We apply the formalism of quantum cosmology to models containing a phantom field. Three models are discussed explicitly: a toy model, a model with an exponential phantom potential, and a model with…

### A PROBLEM OF COSMOLOGICAL TIME IN THE DE SITTER SPACE-TIME

- Computer Science
- 2015

Since the generalized representation of de Sitter solution does not constrain the values of integration functions, there are infinitely many such synchronous coordinate systems and, therefore, the matching ofde Sitter solutions and general Tolman solution is possible and it is impossible to introduce a notion of universal cosmological time in the de Sitters Universe.

It is shown that cyclic models require a comparable degree of tuning to that needed for inflationary models, and the constraints are reduced to a set of simple design rules including "fast-roll" parameters analogous to the "slow- roll" parameters in inflation.

We find that sudden future singularities of pressure may also appear in spatially inhomogeneous Stephani models of the universe. They are temporal pressure singularities and may appear independently…
