The Chinese-led HyperMillennium project has recently made waves in the scientific community, marking a significant milestone in the country's cosmological simulation and supercomputing capabilities. This ambitious endeavor, led by scientists at the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), has achieved what many thought impossible: a fully domestic, end-to-end solution for cutting-edge cosmological research. What makes this project truly remarkable is not just its scale, but also the level of independence and innovation it embodies. Personally, I find it fascinating that China has managed to break free from its reliance on foreign computing resources, and instead, has developed its own software and hardware solutions. This shift is not just a technical achievement; it's a strategic move that positions China as a leader in the field of digital simulation, potentially reshaping the global landscape of scientific research. What makes this particularly intriguing is the project's use of PhotoNs, a software developed independently by the NAOC team. This software, combined with domestic supercomputers, has enabled the team to achieve long-duration computing capabilities using tens of thousands of accelerator cards. In the past, researchers would often import ready-made codes from abroad and cooperate with domestic computing centers, but the HyperMillennium project has taken a completely different approach. From the design of the scientific project to the deep integration with domestic hardware, everything was built independently from scratch. This level of self-reliance is not only impressive but also carries landmark significance. The project's achievements have been hailed as a 'computational marvel' by international peers, and for good reason. By simulating a virtual universe with a side length of 12 billion light-years and using 4.2 trillion virtual dark matter particles, the team has accurately recreated the evolution of large-scale structures in the universe over 10 billion years. This simulation provides theoretical support for research into dark matter and dark energy, and offers strong support for new-generation galaxy survey programs, such as the China Space Station Telescope and the European Space Agency's Euclid mission. The implications of this project are far-reaching. By comparing a high-precision virtual universe with real-world observations, the HyperMillennium project provides important support for research into fundamental cosmological questions such as dark matter and dark energy, while deepening our understanding of the laws governing galaxy evolution. Moreover, its simulation data will offer crucial scientific support for major sky survey projects, including the China Space Station Telescope and the European Space Agency's Euclid space telescope. What many people don't realize is that cosmological simulations, while highly sophisticated, are closely connected to the public. The results of numerical simulations are essentially abstract data, but they can be transformed through visualization into smooth, cinematic, and visually striking images. These images can vividly show the history of cosmic evolution, large-scale structures, and the formation of important celestial bodies, presenting a complete history of the universe. Leveraging this capability, the Qianyan project has already partnered with various institutions to convert data into films, images, and artistic creations for science popularization. This approach not only presents the appearance of the universe to the public in a direct and credible way, but also carries significant implications for science communication and cultural outreach. In conclusion, the HyperMillennium project is more than just a scientific achievement; it's a testament to China's growing influence in the field of digital simulation and its potential to reshape the global landscape of scientific research. As we move forward, it will be fascinating to see how this project continues to push the boundaries of what's possible in numerical cosmology and how it will impact our understanding of the universe.
