Astrophysicists Masao Mori and Masayuki Umemura have used the powerful computer “Earth Simulator” to analyze the evolution of galaxies.
This computer is mainly used to develop climate models. This time it has been used to make the greatest calculation in astrophysics. They have analyzed how galaxies have changed from 300 million years after the Big Bang to the present day.
The dynamic and chemical processes that occur since the birth of galaxies have been taken into account. And seeing the results, astrophysicists have been surprised by either side. For example, the current composition of the Milky Way was not expected to be similar to that of a billion years ago. Until now it was thought that galaxies evolved little by little and were enriched with heavy elements as stars and supernovae emerged.
According to Mori, his calculations show that galaxies have evolved rapidly and have not taken more than a billion years to produce large quantities of heavy elements.
The image above, published in the journal Nature, among other results, shows the appearance of stars, gases and metals 100 million years, 300 million, 500 million and one billion years of the Big Bang.
