Scientists have created the most extensive and detailed computer simulation of the universe in history. It is called Uchuu (Japanese for “Outer Space”) and is available for download.

The cosmic simulation contains 2.1 trillion particles in the space of 9.6 billion light-years across and represents the universe's evolution throughout 13 billion years.

Astronomers First Spot Light Behind a Supermassive Black Hole
This discovery confirms the general theory of relativity, according to which the gravitational attraction of black holes warps space, bends light rays, and twists magnetic fields around itself, allowing you to see the light echo.

Since the computer model is highly detailed, it allows scientists to identify various objects ranging from clusters of galaxies to stellar halos of individual galaxies. The simulation mainly focuses on the behavior of dark matter and dark energy within the expanding universe.

It took enormous computational power and storage to create such a detailed virtual universe. Scientists used over 40,000 computer cores and 20 million computer hours to create the Uchuu simulation. It ended up producing more than 3 petabytes (3 thousand terabytes or 3 million gigabytes) of data.

Scientists Recorded Glowing Rings Around a Black Hole
The observatory snapped a picture of the black hole in conjunction with the Neil Gehrels Swift Observatory, which is jointly run by the United States, Italy, and the United Kingdom. Scientists managed to detect the rings precisely by capturing X-rays.

With high-density compression, the team managed to compress the obtained data to 100 terabytes.

The raw data on the Uchuu simulation can be found here.
