Scientists recreate the first 2 billion years of the Universe with Lumina simulation

Scientists at the Center for Astrophysics | Harvard & Smithsonian have created "Lumina," one of the largest and most detailed simulations of the early universe. This groundbreaking model reconstructs the first 2 billion years after the Big Bang, showing the interactions between dark matter, gas, and radiation that led to the formation of the earliest stars, galaxies, and black holes. It will serve as a powerful tool for interpreting observations from telescopes like JWST and the Nancy Roman Space Telescope.
