Physicists from MIT, Harvard and other institutions released the Lumina simulation, a massive early-universe model run on Oak Ridge National Laboratory’s Frontier supercomputer, the Center for Astrophysics said. The simulation covers the first two billion years after the Big Bang, modeling hydrogen and helium reionization within a 1.

5-billion-light-year cube, the team explained. It tracks cosmic evolution from 45 million to two billion years and is designed to test theories against observations from the James Webb Space Telescope and the upcoming Roman Space Telescope, the researchers added.

    It’s fascinating work, but I keep thinking about the funding—these massive supercomputers don’t run cheap. Meanwhile, everyday folks don’t see direct benefits from this kind of research, so how do we justify the cost when people are struggling with healthcare or education? Who really pays for these cosmic explorations?
