   Lumina Simulation Reveals Early Universe on Record-Breaking Scale

   Researchers at the Center for Astrophysics, Harvard and Smithsonian have developed a massive supercomputer simulation called Lumina to model the first two billion years of the universe. Created to help astronomers interpret observations from the James Webb Space Telescope and the Nancy Roman Space Telescope, Lumina maps the cosmic web and illustrates how the earliest galaxies, stars, and structures emerged from the dark ages following the Big Bang. The simulation covers a scale of 1.5 billion light-years, offering unprecedented detail on primordial plasma, neutral hydrogen, and cosmic evolution.

   Why it matters

   Early cosmic discoveries made by the James Webb Space Telescope have baffled scientists and triggered the creation of advanced testing tools like Lumina. The universe began as a hot and dense soup of electrons and subatomic particles that expanded, cooled, and eventually allowed neutral hydrogen to form. Supercomputer models like this provide essential frameworks for testing reality against modern deep-space observations.

   What is confirmed

   • Researchers at the Center for Astrophysics, Harvard and Smithsonian developed Lumina to simulate the early universe.
   • Lumina models the first two billion years of the universe, covering a scale of 1.5 billion light-years.
   • The simulation was created to help astronomers understand observations from the James Webb Space Telescope and Nancy Roman Space Telescope.

   Still unconfirmed

   • The simulation was specifically triggered by baffling early cosmic discoveries made by the James Webb Space Telescope to test reality.

   What to watch next

   • Further scientific analysis comparing Lumina simulation outputs with James Webb Space Telescope data
   • Additional findings from the Nancy Roman Space Telescope regarding the universe's earliest chapters
