The fundamental parameters of the Universe might be universally constant. But they might also be 'constants' set by a simulation... or a simulator.

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

A team of astronomers have developed a computer simulation called "Illustris," which took five years to program and, for the first time, can recreate the evolution of the Universe in high fidelity.

Is the universe just an enormous, fantastically complex simulation? These were the big questions that a group of scientists, as well as one philosopher, tackled on April 5 during the 17th annual ...

VIRTUAL UNIVERSE In a snapshot from the Illustris computer simulation of the universe, galaxies (pink) cluster along filaments of dark matter (blue). Shown is the most massive cluster in the ...

Simulation of the standard cosmological model has already allowed researchers to discover a number of important properties concerning the distribution of matter in the universe.

The simulation traces the evolution of the large-scale structure of the universe, including the evolution and distribution of the dark matter halos in which galaxies coalesced and grew.

By strengthening the galactic winds in a computer simulation of the entire history of the universe, astronomers may have a more accurate model with which to study galaxies and their evolution.

The simulation takes into account that there are phenomena in our universe that we have never detected but that have had huge influence on cosmic evolution.

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