Simulation shows how universe formed in stunning detail: new reserach

Key Points:

• Astronomers have created the most detailed simulation of the universe's first two billion years, called the Lumina model, developed by the Center for Astrophysics in collaboration with the Smithsonian Astrophysical Observatory and Harvard College Observatory.
• The simulation depicts the early universe as a 1.5 billion light-year cube filled with dark matter filaments and luminous gas, illustrating how these elements combined to form early cosmic structures.
• Utilizing over 15,000 graphics processing units on the Frontier supercomputer, the Lumina model covers a volume more than 100 times larger than previous simulations while resolving individual galaxies and black holes.
• Researchers plan to compare Lumina’s predictions with observations from the James Webb Space Telescope and other instruments to test and refine theories about the universe's early evolution.
• The project marks a significant advancement in astrophysics by translating complex cosmic theories into detailed visual predictions, aiding scientists in interpreting new telescope data.
