Lumina simulation traces the universe’s first two billion years

The New York Post describes Lumina as a simulation of the universe’s first two billion years, created through a collaboration between the Smithsonian Astrophysical Observatory and Harvard College Observatory. The project used more than 15,000 graphics processing units running on Frontier, a supercomputer at Oak Ridge National Laboratory in Tennessee.

  • First 2 billion years of universe’s existence revealed in mind-blowing simulation: ‘Exciting new frontier’

The brief

Lumina models the universe’s first two billion years, using more than 15,000 graphics processing units running on Frontier, a supercomputer at Oak Ridge National Laboratory in Tennessee, according to the New York Post. The outlet describes the simulation as portraying cosmic evolution from a nebulous, gas-filled cube into a complex network of galaxies and black holes.

The project’s video was created through a collaboration between the Smithsonian Astrophysical Observatory and Harvard College Observatory. The New York Post says the video opens with the universe represented as a cube measuring 1.5 billion light-years on each side. The simulation then presents the universe at an age of 1.5 billion years.

The New York Post describes that scene as filled with fine filaments of dark matter and luminous gas, and says the researchers’ model depicts the universe’s development during its first two billion years after the Big Bang. The New York Post identifies the Center for Astrophysics as the organization behind the model.

It also reports that the video recreates the early universe, describing the project as a computer simulation rather than a direct image of the period it represents. Dr.

Aaron Smith, a physicist at the University of Texas at Dallas and a co-author of a paper in the Monthly Notices of the Royal Astronomical Society, said the team felt fortunate to be developing simulations like Lumina. His comment is the only quoted reaction included in the outlet’s account.

The work’s computing demands are reflected in its use of more than 15,000 graphics processing units on Frontier. The New York Post calls Frontier one of Earth’s fastest supercomputers and locates it at Oak Ridge National Laboratory in Tennessee.

A Smithsonian headline separately describes the project as the most detailed simulation yet of the early universe; AZoQuantum’s headline says Lumina traces how particles formed the early ionized universe.

Why it matters

  • Lumina’s depiction connects the early universe’s dark matter and luminous gas filaments with the later network of galaxies and black holes.
  • The simulation’s computing requirements are substantial: it ran on more than 15,000 graphics processing units using Frontier.
  • The project involved the Smithsonian Astrophysical Observatory and Harvard College Observatory, and Dr. Aaron Smith described its development as an effort the team felt fortunate to pursue.

What to watch next

  • Whether the Smithsonian Astrophysical Observatory or Harvard College Observatory provides further details about the Lumina collaboration.
  • Whether Dr. Aaron Smith and his co-authors publish additional findings about the simulation in the Monthly Notices of the Royal Astronomical Society.
  • Whether the Smithsonian provides more information about its headline description of Lumina as the most detailed simulation yet of the early universe.
