In this paper we present a new simple method of construction of infinite number of solutions of Freidmann equations from the already known ones, which allows for a startling conclusion of practical impossibility of correct predictions on the universe's future dynamics which are based solely on astronomical observations on the value of a scale factor. In addition, we present particular examples of newly constructed solutions, such as the ones, describing the smooth dynamical (de)-phantomization, and the models lacking the events horizons (both in classical and brane world cases). The generalization of the method to the simplest anisotropic universes are presented as well.
