The largest-ever simulation of the universe has just been released

Summary

The article discusses the release of Flagship 2, the largest-ever simulation of the universe, created to aid in the analysis of data from the Euclid space telescope. The simulation maps 3.4 billion galaxies and tracks the gravitational interactions of over 4 trillion particles. Researchers anticipate that Euclid's observations will challenge the standard cosmological model, particularly regarding dark energy.

Key Takeaways

1. The Euclid Consortium published Flagship 2, the world's most extensive simulation of the universe, mapping 3.4 billion galaxies and tracking over 4 trillion particles.
2. Simulations like Flagship 2 help speed up processing times for the vast quantities of data produced by the Euclid space telescope.
3. Euclid's observations, looking up to 10 billion years in the past, might reveal different characteristics of dark energy and challenge the standard cosmological model.
