Chinese scientists have created a digital virtual universe to completely recreate the evolution of the universe over 13.8 billion years.

On April 23, the National Astronomical Observatory of China, Chinese Academy of Sciences, released the cosmological simulation project "Qianyan". Led by Chinese scientists, an international team successfully built a digital virtual universe on a supercomputer, providing a high-precision digital guide map for human exploration of the mysteries of the universe and the study of the historical evolution of the universe. The so-called digital virtual universe refers to a digital universe built by researchers using the powerful computing power of a supercomputer that is very similar to the real universe. This digital universe faithfully reproduces the evolution process of the universe from its birth to the present day over billions of years, capturing the appearance of each stage in the form of digital models. It is understood that in this research work lasting more than a decade, Chinese research teams used independently developed software, optimized algorithms, programming, and other aspects for domestically produced supercomputers, ultimately producing a total of 13 PB of research data, fully demonstrating China's innovative capabilities in computational cosmology and high-performance computing, helping the field of cosmology research worldwide enter the era of high precision.
