When we experience the world, we believe it’s an accurate reflection of reality. But what if it’s all an illusion? From the ...

Simulations based on Einstein’s theory of relativity test scenarios that might have preceded the Big Bang, to observe the ...

For decades, astronomers have wondered what the very first stars in the universe were like. These stars formed new chemical ...

For decades, astronomers have been working to explore the properties of the first generation of stars in the universe. These stars created new chemical elements, enriched the chemical composition of ...

A supercomputer at Oak Ridge National Laboratory in the US has just pulled off the largest astrophysical simulation of the Universe accomplished to date. In November 2024, physicists used 9,000 ...

Pictures are the key to new insights in the field of astrophysics. Such images include simulations of cosmic events, which ...

Researchers have created what they say is the largest computer simulation of the universe, and have made the data available for anyone to download for free. "Uchuu is like a time machine: we can ...

Of some help could be a new computer simulation that traces how all elements of the universe — ordinary matter, dark matter and dark energy — evolve according to the laws of physics.

The findings could have implications for the speculative possibility that the universe is actually a gigantic computer simulation. Underlying the mind-boggling number is an even stranger hypothesis.

Researchers are using unprecedented calculations to develop a simulation of what the universe looked like about 400,000 years after the Big Bang.

An international collaboration of astronomers has created the most detailed simulation yet of the early stages of the universe.

The Bolshoi supercomputer simulation, the most accurate and detailed large cosmological simulation run to date, gives physicists and astronomers a powerful new tool.
