Stationary Universe

چکیده
If the Universe contains at least one inflationary domain with a sufficiently large and homogeneous scalar field φ, then this domain permanently produces new inflationary domains of all possible types. We show that under certain conditions this process of the self-reproduction of the Universe can be described by a stationary distribution of probability, which means that the fraction of the physical volume of the Universe in a state with given properties (with given values of fields, with a given density of matter, etc.) does not depend on time. This represents a strong deviation of inflationary cosmology from the standard Big Bang paradigm.

From the big bang theory to the theory of a stationary universe.
We consider chaotic inflation in the theories with the effective potentials which at large φ behave either as φ or as e. In such theories inflationary domains containing sufficiently large and homogeneous scalar field φ permanently produce new inflationary domains of a similar type. This process may occur at densities considerably smaller than the Planck density. Self-reproduction of inflationa...
متن کاملGenerating New Magnetic Universe Solutions from Old
In this paper we apply the techniques which have been developed over the last few decades for generating nontrivially new solutions of the EinsteinMaxwell equations from seed solutions for simple spacetimes. The simple seed spacetime which we choose is the “magnetic universe” to which we apply the Ehlers transformation. Three interesting non-singular metrics are generated. Two of these may be d...
متن کاملHomogeneous Cosmologies from the Quasi-maxwell Formalism
We show how to use the quasi-Maxwell formalism to obtain solutions of Einstein’s field equations corresponding to homogeneous cosmologies – namely Einstein’s universe, Gödel’s universe and the Ozsvath-Farnsworth-Kerr class I solutions – written in frames for which the associated observers are stationary.
متن کاملA one-parameter family of cylindrically symmetric solution approaching Einstein’s universe
In this note we describe a stationary cylindrically symmetric solution of Einstein’s equation with matter consisting of a positive cosmological constant and an infinite cylinder of rotating dust. The solution approaches Einstein static universe solution. This result is complementary to Iftime [Class Quantum Grav 19 (2002)].
متن کاملThe Big Bang Quantum Cosmology: the Matter-energy Production Epoch
The exactly solvable quantum model of the homogeneous, isotropic and closed universe in the matter-energy production epoch is considered. It is assumed that the universe is originally filled with a uniform scalar field and a perfect fluid which defines a reference frame. The stationary state spectrum and the wave functions of the quantum universe are calculated. In this model the matter-energy ...
