(T) I do remember a while ago that Professor Alan Guth from MIT, the father of the Inflationary Universe Theory, said that the next step in better understanding the evolution of the Universe was to simulate it. Well…c’est chose faite…now with Illustris!
Last month, a collaboration of researchers from MIT, the Harvard-Smithsonian Center for Astrophysics, the Heidelberg Institute for Theoretical Studies in Germany, and many other institutions published the details of their time machine to recreate our cosmic evolution from its early beginning to the present. What a journey!
“The Illustris simulation is the most ambitious computer simulation of our Universe yet performed. The calculation tracks the expansion of the universe, the gravitational pull of matter onto itself, the motion of cosmic gas, as well as the formation of stars and black holes. These physical components and processes are all modeled starting from initial conditions resembling the very young universe 300,000 years after the Big Bang and until the present day, spanning over 13.8 billion years of cosmic evolution. The simulated volume contains tens of thousands of galaxies captured in high-detail, covering a wide range of masses, rates of star formation, shapes, sizes, and with properties that agree well with the galaxy population observed in the real universe. The simulations were run on supercomputers in France, Germany, and the US. The largest was run on 8,192 compute cores and took 19 million CPU hours. A single state-of-the-art desktop computer would require more than 2000 years to perform this calculation.”
