Stationary Universe
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 phys...
متن کاملStationary Universe Model : Inputs and Outputs 1
In our opinion, the simplest and, simultaneously, the most general version of inflationary cosmology is the chaotic inflation scenario. It can be realized in all models were the other versions of inflationary theory can be realized (see [4] for detailed account). Several years ago it was realized that inflation in these theories has a very interesting property which will be discussed in this ta...
متن کاملTowards the Theory of Stationary Universe.
This talk presents some progress achieved in collaboration with A.Linde and D.Linde towards understanding the true nature of the global spatial structure of the Universe as well as the most general stationary characteristics of its timedependent state with eternally growing total volume. In our opinion, the simplest and, simultaneously, the most general version of inflationary cosmology is the ...
متن کاملA spherically symmetric and stationary universe from a weak modification of general relativity
It is shown that a weak modification of general relativity, in the linearized approach, renders a spherically symmetric and stationary model of the universe. This is due to the presence of a third mode of polarization in the linearized gravity in which a “curvature” energy term is present. Such an energy can, in principle, be identified as the Dark Energy. The model can also help to a better un...
متن کاملFrom 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...
