But, with upgrades making Frontier the fastest supercomputer in the world at the time, the team was able to increase the size of their simulation to model the expansion of the Universe.

Argonne National Laboratory scientists performed the most extensive simulation of the cosmos on Frontier supercomputer. What happened next?

The world's second fastest supercomputer — it used to be the fastest, before its rival machine came online earlier this month — has created the most complex computer simulation of the universe ...

Scientists have used the world's fastest supercomputer to create the largest simulation of the cosmos ever created.

Constituting 70% of the total energy of the Universe (the remaining 30% is made of dark matter and ordinary matter), it is responsible for the accelerated expansion of the Universe.

“The hypothesis that we live in a simulation seems provable: it could be the discovery of a flaw in the simulation, such as a distant region of the universe that cannot be zoomed in on, where a ...

Studying the violent collisions of black holes and neutron stars may soon provide a new measurement of the Universe’s expansion rate, helping to resolve a long-standing dispute, suggests a new ...

And by studying the simulation’s 100 million synthetic galaxies, they will see how galaxies and galaxy clusters evolved over eons. Repeated mock observations of a particular slice of the universe ...

It is a notion that seems like science fiction —but one that is based in physics and evidence that the universe appears to be operating suspiciously like a computer simulation.

A simulated universe created by a supercomputer should help astronomers better analyze dark matter and dark energy clues delivered by "dark universe detective" telescopes Roman and Rubin.
