Supercomputers have run the most accurate simulation of the universe

Supercomputers have run the most accurate simulation of the universe

The age of the universe as we know it is 13.7 billion years. According to current knowledge, all astronomical events can be explained by the behavior of dark matter condensing into clusters known as the corona. This is called cold dark matter model (CDM), which hypothesizes that the accumulation of gases and other matter around the corona leads to the formation of stars and galaxies.

Most of the previous simulations are based on the CDM hypothesis Focused on random parts of the skyNot in our cosmic neighborhood. Scientists set out to see if the CDM could be used to accurately reproduce the region of space surrounding the Milky Way.

Astrophysicists presented the equations describing the CDM model to a supercomputer DiRAC Beauty Machine (COSMA)It is located at Durham University. Using the data entered, the supercomputer proceeded to simulate the entire history of a portion of the sky It extends 600 million light years from the solar system, represented by more than 130 billion particles. This region is home to the clusters of galaxies Virgo, Perseus, and Abell 1656, as well as structures such as the Local Void and the Great Sloan Wall. After carefully checking the simulations performed, the scientists concluded that the model was accurate.

Simulations simply reveal the consequences of the laws of physics operating on dark matter and space gas over the 13.7 billion years since our universe. The fact that we were able to recreate these known structures provides impressive support for the standard CDM model and tells us that we are well on our way to understanding the evolution of the entire universe,” said study co-author Carlos Frink.

The model known as Dark Sibelius revealed that our local slice of the universe has a “very low density” of dark matter compared to the cosmic average. However, the simulations performed do not challenge the CDM model.
