[4K高清短片] Illustris模拟宇宙的进化 2014 [2880P/MKV/303MB]

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项目是一个非常详细的和现实的宇宙模拟宇宙中星系的形成由一个才华横溢的研究人员和科学家群体。 从本质上讲，这是一个计算机模型，旨在构建虚拟宇宙基于我们知道这些事情，和那些项目建造遵守规则，因为他们目前理解的非常好。 仍然有一些异常的模拟，然而，如低质量星系建立太快。
根据马克Vogelsberger物理学家麻省理工学院(MIT)模拟背后的人之一，当前的顶级PC需要近2000年来处理必要的数据，和8000个处理器使用的仿真花了几个月。
计算跟踪宇宙的膨胀，物质的引力在本身、宇宙气体的运动、以及恒星和黑洞的形成。 这些物理组件和流程建模从初始条件类似于非常年轻的宇宙大爆炸后300000年，直到今天，跨越了138亿年的宇宙演化。 模拟卷包含成千上万的星系在high-detail捕获，覆盖范围广泛的群众的恒星形成率、形状、大小和人口属性，同意与星系中观察到真正的宇宙。
