The first-ever artificial intelligence simulation of the universe seems to work like the real thing — and is almost as mysterious.

The goal was to create a virtual version of the cosmos in order to simulate different conditions for the universe’s beginning, but since computer modeling were too slow, the scientists created a deep neural network with traditional but brand-new, never-before-seen simulations of a virtual, cube-shaped universe 600 million light-years across, to speed up the process.

The neural network was able handle the simulations despite never being trained on how to handle the new details, furthermore, the new neural network could complete simulations in 30 milliseconds, compared to several minutes for the fastest non-artificial intelligence simulation method.
