Scientists have unveiled Lumina, a groundbreaking supercomputer simulation that recreates two billion years of early cosmic history across a region 1.6 billion light-years wide. The project, detailed in a new study, aims to explain how the universe emerged from its cosmic dark age, a mysterious epoch before the first stars and galaxies ignited. According to the research team, Lumina captures extraordinary levels of detail that previous simulations could not achieve, offering an unprecedented window into the processes that transformed a cold, dark cosmos into one filled with light.
The simulation traces the formation of the earliest stars and galaxies and their role in reionizing the universe, a pivotal transition that ended the dark age. Researchers say Lumina's resolution allows them to model the complex interplay of gravity, gas dynamics and radiation at scales previously unattainable, potentially resolving long-standing questions about how cosmic structure evolved. The findings are expected to inform and complement upcoming observations from next-generation telescopes. The team has made data from the simulation available to the broader astronomical community, and further studies are planned to explore additional epochs of cosmic history.
