""It is exhilarating to see 'galaxies' come out of our computer that look indistinguishable from the real thing and share many of the properties that astronomers measure in real data such as their number, luminosities, colors and sizes.""
""What is most remarkable is that we are able to produce this synthetic universe purely by solving the relevant equations of physics in the expanding universe.""
""The researchers say their virtual universe demonstrates that the standard model can explain galaxy formation even better than previously thought - a welcome source of respite, as recent discoveries... have poked holes in the prevailing model.""
""The international team spent nearly ten years building the COLIBRE model, which they ran on the COSMA8 supercomputer at Durham University, taking 72 million CPU hours to complete the largest simulation.""
Astronomers developed a synthetic universe, known as the COLIBRE project, to test the standard cosmological model. This simulation reproduces properties of the real universe, including galaxy characteristics. Researchers found that their model could explain galaxy formation more effectively than previously thought, addressing concerns raised by recent discoveries. The simulation uniquely modeled cold gases and cosmic dust, overcoming previous limitations. The project took nearly ten years and utilized significant computing resources, marking a significant advancement in cosmological simulations.
