Scientists and astronomers have been studying how galaxies form for a long time and have a new tool to try and figure out how formation happens. A team from the University of Arizona is closer to answering those questions thanks to a new computer simulation they have developed. One challenge for researchers is that studying real galaxies only gives a snapshot in time.
This study is the first to create self-contained universes that are such exact replicas of a real galaxy. The simulations each represent a big chunk of the actual cosmos with 12 million galaxies spanning the time from 400 million years after the Big Bang to today. Each of the “Ex-Machina” universes was put through a series of tests to evaluate how similar galaxies appeared in the generated universe compared to the real universe.
