MIT researchers present Lumina simulation of the early universe
The research team’s new simulation follows matter and radiation through early cosmic history and is intended for comparison with telescope observations.
What the record says
MIT’s October 26 report describes Lumina, a computer simulation developed by researchers at MIT, Harvard and other institutions. It models dark matter, gas, stars and radiation across a region about 1.6 billion light-years wide, tracing roughly two billion years of cosmic evolution. The team says the model follows both hydrogen and helium reionization and ran on the Frontier supercomputer at Oak Ridge National Laboratory. The researchers are making the work available to other scientists for comparison with observations.

Limits and what is not established
These are computer-model results based on physical assumptions, not direct images or observations of every simulated event. Comparisons with telescope data are part of assessing the model.
