Largest-ever simulation of the universe created by scientists, spanning 12 billion light years.

Scientists have created the largest and most accurate digital simulation of the universe, which can be rewound to 100 billion years ago to witness the birth of the cosmos and predict the future evolution of the universe. Known as the "Qianyan" project, this cutting-edge technology reveals the mysteries of the universe simulation. Today, the research team from the National Astronomical Observatory has released the largest-scale universe simulation project in the world - Qianyan. Scientists have created a digital simulation universe with a scale of 120 billion light-years, consisting of 4.2 trillion dark matter particles inside a supercomputer, breaking the limits of global digital universe volume and accuracy.
