Utilizing the Frontier supercomputer, the model traces the formation of the first stars and galaxies and the reionisation of the early universe. Lumina reconstructs interactions between radiation, dark matter, and ordinary matter, covering 100 times more volume than previous runs. The simulation provides a framework to interpret observations from advanced telescopes and test the existence o
