The Illustris project is an incredibly detailed and realistic cosmological simulation of the formation of galaxies in our Universe by a talented group of researchers and scientists. Essentially, it’s a computer model designed to build virtual universes based on what we know about such things, and the ones that the project constructed follow the rules as they are currently understood remarkably well. There are still some anomalies in the simulations, however, such as low-mass galaxies building up too soon.
According to Mark Vogelsberger, a physicist at the Massachusetts Institute of Technology (MIT) and one of the people behind the simulation, a current top-of-the-line PC would take nearly 2,000 years to process the necessary data, and the 8,000 processors that the simulation used took several months to do so.
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.
Illustris項目是一個非常詳細的和現(xiàn)實的宇宙模擬宇宙中星系的形成由一個才華橫溢的研究人員和科學家群體。 從本質(zhì)上講，這是一個計算機模型，旨在構建虛擬宇宙基于我們知道這些事情，和那些項目建造遵守規(guī)則，因為他們目前理解的非常好。 仍然有一些異常的模擬，然而，如低質(zhì)量星系建立太快。
根據(jù)馬克Vogelsberger物理學家麻省理工學院(MIT)模擬背后的人之一，當前的頂級PC需要近2000年來處理必要的數(shù)據(jù)，和8000個處理器使用的仿真花了幾個月。
計算跟蹤宇宙的膨脹，物質(zhì)的引力在本身、宇宙氣體的運動、以及恒星和黑洞的形成。 這些物理組件和流程建模從初始條件類似于非常年輕的宇宙大爆炸后300000年，直到今天，跨越了138億年的宇宙演化。 模擬卷包含成千上萬的星系在high-detail捕獲，覆蓋范圍廣泛的群眾的恒星形成率、形狀、大小和人口屬性，同意與星系中觀察到真正的宇宙。
