Largest Calculation of Astrophysics

The astrophysicists Masao Mori and Masayuki Umemura have used the powerful Land Simulator computer to analyze the evolution of galaxies.
Although the land simulator is mainly used for the development of climatic models, this time it has been used to make the greatest calculation of history in astrophysics. Specifically, they have analysed how galaxies have changed from 300 million years after the Big Bang to the present day.
For this purpose, the dynamic and chemical processes that occur since the birth of galaxies have been taken into account. And among the results there are amazing things. For example, the present 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 gradually evolved and were enriched by heavy elements as the stars emerged and the supernovae exploded.
According to astrophysicists, the simulation shows that galaxies have evolved rapidly and have not taken more than a billion years to produce large quantities of heavy elements.
