A vast new simulation illuminates the universe’s early darkness

So, researchers have created Lumina, a remarkable simulation that follows two billion years of cosmic history across a region about 1.6 billion light-years wide. It shows how the first stars and galaxies helped ionize hydrogen, while actively feeding supermassive black holes supplied the energy to ionize helium. By capturing both transformations together, Lumina offers a more complete picture of how the early universe became transparent to light. And here's the thing: scientists are sharing it with researchers worldwide, so its predictions can be tested against telescope observations.
