Evolution of the most massive galaxy cluster in the high-resolution simulation. The main frame shows the gas density (brightness) and temperature (hue), with white indicating the hottest and densest ...

A small group of young researchers at the Cosmic Dawn Center, Niels Bohr Institute, University of Copenhagen, have, through ...

A new research paper reframes the simulation hypothesis, asking whether reality could be simulated and what science can test.

When scientists push the limits of the world's most powerful supercomputers, they often find those limits are just the beginning of what's possible. In early November, the Department of Energy's ...

A projection through a 130 million light years thick slice through a simulation of a cubic volume of 9,132 million light years on a side. The luminosity of the background image gives the cold dark ...

In a mesmerizing display of scientific artistry, NASA has unleashed a stunning simulation that takes viewers on an awe-inspiring journey through the history of the universe. While the universe's ...

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

Scientists made a twin version of our universe, showing the evolution of all forms of matter and energy, in the biggest cosmological computer simulation to date. When you purchase through links on our ...

Since the gravitational waves predicted by Einstein were first detected in 2015, astrophysicists have been pondering the gravitational wave background—the cumulative undulations of these spacetime ...

The simulation hypothesis—the idea that our universe might be an artificial construct running on some advanced alien computer—has long captured the public imagination. Yet most arguments about it rest ...

There may be something wrong with our models of the cosmos. The matter in the universe is getting clumpier and clumpier over time but it appears to be happening more slowly than expected. This ...
