New models compute mysterious 'force' 25 times faster

Dark energy is a phrase used by physicists to describe a mysterious'something' that is causing the universe to accelerate in its expansion. It is the'gravitational glue' that holds galaxies together and is thought to make up five sixths of the universe's mass. These substances have profound effects on the birth and lives of galaxies and stars and yet almost nothing is known about their physical nature. But now a new computer model, twenty-five times faster than other methods, will allow scientists to compute virtual universes in the search of explanations about these mysteries. The new method makes the universe models more accurate by comparing the model's properties with an'inverted' version.
