While some scientists wanted to create a life simulation to predict the future, others uses a similar technology to create digital impression of model the whole universe to look back and figure out what happened to the universe in the last billion years. Thanks to a 1024-core supercomputer, a group of researchers decided to recreate the whole process of development of the cosmos, ranging from the Big Bang to the present moment in which we live. The bold initiative arose from a partnership of the Center for Astrophysics, Harvard-Smithsonian with the Institute for Theoretical Studies of Heidelberg, which has shaped thousands of stars and galaxies to get a result very close to reality. For this, they used a program called Arepo, which allowed the creation of the elements you see in the video above.
However, do not think that all this was easy. Although the presentation is brief and has little more than a minute, it is based on months of image processing, especially for your understanding.
According to the researchers, the next step is to bring a similar but more extensive video, covering larger areas of the universe, showing the creation and development of galaxies and other celestial bodies.
