[The Epoch Times, February 16, 2022](The Epoch Times reporter Di Rui compiled and reported) A group of scientists followed thestandard model of the universetheory, usesupercomputerEvolution generates a simulated universe. The study said the simulations showed the best agreement with actual observations of any model to date.at thiscomputer simulationuniverse with our Milky Way at its center.
Researchers from the University of Helsinki led the study. The model they built shows the shape of the universe in space 600 million light-years from Earth, made up of more than 130 billion simulated particles. It took tens of thousands of computers connected to work for weeks to calculate and generate this model.
There are several different theories about how the universe was born, the most popular of which is “standard model of the universe“, which refers to an unknown “dark matter” concept, that dark matter plays an important role in the evolution of galaxies and various large-scale cosmic structures.
Simply put, the Standard Model of the Universe says,dark matterFirst, the clusters gather together, and then the surrounding gas is attracted to get close to these dark matter clusters. Gradually, the gas interacts and separates from each other to form stars, which in turn form galaxies. During this process, the dark matter continues to expand around these galaxies, and eventually remains around the galaxies, just like the Milky Way we see now, surrounded by a dense circle of dark matter.
In the past 20 years, most scientists have gradually agreed with and accepted this evolutionary model, and have continued to improve it. This model can explain not only the shape and distribution of matter in the universe observed today, but also another key set of data—radiation data from the early days of the universe.
After the results of this simulation were produced, the research team compared the actual data, such as the morphology of some large galaxies and their distribution characteristics observed with the telescope, with the simulation results. They focused on comparing the conditions of galaxies within the so-called Local Group of galaxies in which Earth and the Milky Way are located.
According to the study, the simulation results correctly evolved galaxies like Virgo, Coma, Perseus, etc., as well as galaxies like the Great Wall, or the Great Wall, which is a The astronomical term for the large-scale structure of the universe), the local void (Local Void) and other giant cosmic structures. The Milky Way and Andromeda are at the very center of the model.
However, the researchers say the model sees fewer galaxies overall in the local galaxy region than the Standard Model thinks. But they believe that this is not enough to question the correctness of the Standard Model of the universe, and that reading the observational data from a different angle may eliminate the discrepancy.
The research was published February 8 in the Monthly Notices of the Royal Astronomical Society. ◇
