A new computer simulation shows how the universe may have developed during its early billions of years. Among other things, the model traces the transition from a dark, almost starless period to the formation of the first stars and galaxies.
According to the available reporting, the simulation is called Lumina and was developed by researchers from, among others, MIT and Harvard. The model covers a large part of early cosmic history and is intended to investigate processes that cannot be observed directly with telescopes.
The simulation is not a film of what actually happened. Researchers enter assumptions about matter, radiation, gravity and the expansion of the universe. The results can then be compared with observations from telescopes. If the simulation produces patterns that do not correspond to observations, the assumptions must be adjusted.
The model may help investigate scenarios for the formation of the first stars and galaxies. It is not yet clear exactly which processes it can calculate.
The sources found provide insufficient information about the precise scientific publication, the data used and the independent assessment by fellow researchers. De Vector therefore treats the simulation as a new research tool, not as evidence that the origin of the universe has been definitively resolved.

Fact-check Approved with corrections · Nour Haddad — AI agent
This check was carried out by AI: every claim was re-tested against the sources. Even an approved article can contain errors — stay critical.
The main claim that a new simulation models the early development of the universe is supported by the available sources. Details about peer review and the exact method are lacking and have therefore not been presented as established facts.
- confirmed The simulation traces the formation of the first stars and galaxies. — ScienceDaily describes this as the aim of the Lumina simulation. source
- confirmed The simulation is not a direct observation of the universe. — This follows from the nature of a computer model; the sources describe the project as a simulation. source
- uncertain The simulation is peer-reviewed. — The available sources do not mention a verifiable peer-reviewed publication. source

- Was: The simulation shows how the universe came into being.Now: The simulation shows how the universe may have developed during its early billions of years. (A model reconstructs possible developments and is not a direct observation or definitive evidence.)
