Title: Inflation, Dark Energy, and the Fate of the Universe

Inflationary theory, which describes an accelerated expansion of the early universe, gradually becomes a standard cosmological paradigm. It solves many complicated problems of the usual big bang theormore »y, explains the origin of galaxies, and makes several predictions, which, so far, are in a good agreement with cosmological observations. Recently we learned that few billion years ago the universe entered the second stage of acceleration, driven by mysterious 'dark energy'. According to the simplest version of inflationary theory, the universe is an eternally existing self-reproducing fractal consisting of different balloons of exponentially large size. The universe as a whole can be immortal, but the fate of each of these balloons, including the one in which we live now, depends on the properties of dark energy. According to some of the theories of dark energy, our part of the universe will continue its accelerated expansion forever. Other theories predict that eventually our part of the universe will become ten-dimensional and stop accelerating. Still another possibility is that our part of the universe will collapse. I will describe recent developments in inflationary theory and the theory of dark energy, and discuss the possibility to find our fate by cosmological observations.« less
