The inflationary universe
نویسنده
چکیده
According to the inflationary universe scenario the universe in the very early stages of its evolution was exponentially expanding in the unstable vacuum-like state. At the end of the exponential expansion (inflation) the energy of the unstable vacuum (of a classical scalar field) transforms into the energy of hot dense matter, and the subsequent evolution of the universe is described by the usual hot universe theory. Recently it was realised that the exponential expansion during the very early stages of evolution of the universe naturally occurs in a wide class of realistic theories of elementary particles. The inflationary universe scenario makes it possible to obtain a simple solution to many longstanding cosmological problems and leads to a crucial modification of the standard point of view of the large-scale structure of the universe.

In this paper, the analytical solutions of Brans-Dicke (B-D) equations with cosmological constant are presented, in which the equation of state of the universe is P=mÙ° ρ , under the assumption φRn=c between the B-D field and the scale factor of the universe. The flat (K=0) Robertson- Walker metric has been considered for the metric of the universe. These solutions are rich in the sense that ...
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 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...
متن کاملQuantum Creation of an Open Inflationary Universe
light years away from each other, so the universe would be practically structureless. We argue that the Hartle-Hawking wave function does not describe the probability of creation of the universe. If one uses the tunneling wave function for the description of creation of the universe, then in most inflationary models the universe should have Ω = 1, which agrees with the standard expectation that...

We describe the universe as a local, inhomogeneous spherical bubble embedded in a flat matter dominated FLRW universe. Generalized exact Friedmann equations describe the expansion of the universe and an early universe inflationary de Sitter solution is obtained. A non-perturbative expression for the deceleration parameter q is derived that can possibly describe the acceleration of the universe ...
