Now You Can Download the Entire Universe… All 3000 TB of It
Always wanted to hold the universe in the palm of your hand? Well, now you can ... as long as you have the file space for it. An international team of scientists has come together to make Uchuu accessible to the public. (We first saw this story on DesignTAXI.) But what is Uchuu? According to the Center for Computational Astrophysics, Uchuu is an unprecedented simulation of our world. They share:
Uchuu (which means “space” in Japanese) is the largest and most realistic simulation of the universe to date. The Uchuu simulation consists of 2.1 trillion particles in a computational cube with an unprecedented side length of 9.63 billion light years. For comparison: That is about three quarters of the distance between Earth and the most distant observed galaxies. Uchuu will enable us to study the evolution of the universe on a previously unimaginable level and level of detail.
A glimpse of this majestic project in action can be seen below:
Basically, Uchuu is a model of the universe. A downloadable model of the universe. It takes a look at large-scale structures. This includes the largest galaxy clusters down to the smallest. And the coolest thing about it? It's almost a space-time machine. Uchuu enables users to enlarge parts of the universe. But it also allows viewers to explore our familiar world over time. "Uchuu simulates the evolution of matter over almost the entire 13.8 billion year history of the universe from the Big Bang to the present." This means that you can go back to the beginnings of existence and look around. It's amazing stuff. To learn more about it, be sure to read the full paper detailing the downloadable universe project.

The creation of Uchuu required immense computing power. And its true size was the equivalent of “894,784,853 images from a 12-megapixel cell phone”. If that sounds like more space than you have on your hard drive, don't worry. The team compressed the universe to just 100 TB. Anyway, a reasonable amount. Especially when you consider that this downloadable universe contains billions of years of data.
Uchuu is designed to interpret future big data galaxy surveys. But there's no reason you can't explore the universe too. You can download Uchuu for free on Github. If you do, send us a postcard from 13 billion years ago. We'd love to see what the universe was like then.
