One of the most difficult to resolve riddles of modern cosmology is the formation of galaxies. How a huge variety of structured and dynamic objects could emerge from the chaos of the Big Bang, is a real puzzle for scientists. Trying to understand exactly how and why it happened that the crucial moment and the mega-explosion of our universe, an international team of scientists have created the most detailed large-scale model of the Universe in the history of mankind. The simulation, called TNG50, is located in the virtual space width of about 230 million light years, with tens of thousands of galaxies, nebulae, stars, black holes and even dark matter.
How does the universe?
TNG50 represents the latest modeling of our Universe created by the project IllustrisTNG, the purpose of which is to build the most complete picture of how our universe evolved after the Big Bang. Incredible resolution and scale has allowed scientists to find key information about the past of our universe, revealing how stellar explosions and black holes caused a real galactic evolution.
Experts from the University of Florida noted that the creation of a unique model of the Universe it took them 16 thousand cores supercomputer Hazel Hen, located in Stuttgart, Germany. In order to perform given the amount of data computer has been running continuously for over a year,the same process would have taken a conventional operating system about 15 000 years. Despite the huge energy costs that accompanied the process, the researchers believe that the results of this experiment are fully paid off. Thus, the project TNG50 allowed the researchers to observe how our galaxy has emerged from a turbulent gas clouds that emerged shortly after the birth of the Universe.
The researchers found that as soon as the gas and dust cloud began to turn into a more or less orderly rotating disks, there began to be another phenomenon. Constant explosions of a supernova and emerging in their place, the supermassive black holes created high-speed flows, which subsequently turned into fountains of gas that rise thousands of light-years above the galaxy. In the future, gravity pulled most of this gas back to the forming galaxy, creating a back loop and flow of matter.
Despite these results, the team from the University of Florida is still far from complete analysis of your model. After all the necessary manipulations for the study of the simulated Universe, experts plan to publish all simulation data in open access for astronomers from around the world.
