Scientists Simulates the Creation of 14 Billion year old Universe

Recreation of Universe
   Are animations of Curiosity's Mars landing not enough to feed your space exploration appetite? Try this on for size: a group of scientists from Harvard-Smithsonian Center for Astrophysics and the Heidelberg Institute for Theoretical Studies have generated what's billed as a full-fledged simulation of the universal.
  Arepo, the software behind this simulation, took the observed afterglow of the big bang as its only input and spread things up by 14 billion years.  The result was a model of the Cosmos peppered with realistically depicted galaxies that look like our own and those around us.

  Arepo's secret to producing accurate visualizations is its geometry; a grid that moves and flexes to mirror the motion of dark energy, dark matter, gasses and stars.  Video playback of the celestial recreation clocks in at just over a minute, but it took Harvard's 1,024 core Odyssey super computer months to churn out.
