Ultimate fate of the universe universe would remain static. After Hubble announced his conclusion that the universe was expanding, Einstein wrote that his cosmological constant was "the greatest blunder of my life." An important parameter in fate of the universe theory is the density parameter, omega (formula_1), defined as the average matter density of the universe divided by a critical value of that density. This selects one of three possible geometries depending on whether formula_1 is equal to, less than, or greater than formula_3. These are called, respectively, the flat, open and closed universes. These three adjectives refer to the overall geometry of the universe,
