Accurate video model of the evolution of the universe: Illustris (+ model of the birth of the galaxy and the end of the universe)

A team of astrophysicists from Cambridge was able to create a fairly reliable model of the evolution of the Universe, starting from the very birth, the Big Bang. It is worth noting that it is almost impossible to develop such a model using a stationary (even if powerful) PC. The fact is that scientists have accumulated a huge amount of factual material about the birth of the universe, so it is a matter of many thousands of years to calculate all this (if you use a stationary PC).

Fortunately, astrophysicists have access to more powerful machines than a home computer. In general, all data was processed on a system with 8 thousand processors. And then, the development of such a model took about five years. The project itself was named Illustris.

The simulation took into account virtually all currently known facts and data, including dark matter, ordinary matter, dark energy, and everything else that is difficult for us, non-specialists, to understand and realize.

In the model of Illustris about 40 thousand galaxies were counted, on a plot of 350 million light years. Similar models were created earlier, but Illustris is the most accurate and large-scale.

By the way, here is another model, this time, of the birth not of the Universe, but of the Galaxy . This model was calculated at the Goddard Space Flight Center.

The model considers the development of a small gas cloud (small on a cosmic scale) into a galaxy, which collides with similar objects, gradually develops, stars are gradually born in a cloud, and the cloud itself turns into a structured formation, a galaxy.



And finally, today I caught the eye of a video model of the end of the universe , created by Joe Henson . This video can not be called an exact model, but as a popular science material worth watching.
