The dressing procedure for the cosmological equations and the indefinite future of the universe

Abstract

We present a new simple method of construction of an infinite number of solutions of the Freidmann equations from already known ones, which allows for a startling conclusion of practical impossibility of correct predictions of the universe's future dynamics which are based solely on astronomical observations on the value of the scale factor. In addition, we present particular examples of newly constructed solutions, such as those describing smooth dynamical (de)phantomization, and models without event horizons (in both the classical and braneworld cases). A generalization of the method to the simplest anisotropic universes is presented as well.
