Synthetic Cosmos Echoes Our Own in a Groundbreaking Computer Simulation

TL;DR Summary
Astronomers have built COLIBRE, a large-volume synthetic universe that reproduces many properties of the real cosmos, including galaxy formation and dust/gas physics, by solving cosmological equations on the COSMA8 supercomputer over about 72 million CPU hours. The decade-long project supports the standard cosmological model by aligning with observations across eras, though it doesn't yet explain the JWST-detected “Little Red Dots” seen in the early universe.
