Astrophysicists from MIT, Harvard and several European institutions have attempted a computer to the creation of the universe shortly after the Big Bang to visualize. The computer model covers a period of 13.8 billion years.

With the model , under the flag of the Illustris Project is realized, researchers have mapped how galaxies form and grow. The research, which for several years has been confiscated, should provide more insight into the structure of the universe. The simulation covers a time span of billions of years, from 300,000 years after the big bang to the present.

The researchers made use of so-called hydrodynamic simulations to calculate. Movements of matter in evolving galaxies Previously this technique, which is very much of processing power, was used only on a limited scale. With Illustris Project researchers made use of supercomputers with 8129 processor cores and memory 25pt for the simulations. That enabled them to then simulate, with tens of thousands of galaxies. A universe with a 27 times larger volume so far

The larger volume and more accurate simulation of galaxies levertde the best simulation of the universe to date. The computer should provide insight into how galaxies are influenced by, among other dark energy, dark matter and normal matter. Thus, among others supported the theory that dark matter is a web along which galaxies can develop.
