Computer simulation. The Sloan Great Wall , the Pisces–Cetus Supercluster Complex , the Horologium-Reticulum Supercluster and the Shapley Supercluster as seen in the 2dF Galaxy Redshift Survey This is a list of the largest cosmic structures so far discovered.
A successful large-scale simulation of the evolution of galaxies, with results consistent with what is actually seen by astronomers in the night sky, provides evidence that the theoretical underpinnings of the models employed, i.e., the supercomputer implementations ΛCDM, are sound bases for understanding galactic dynamics and the history of the universe, and opens avenues to further research.

The Millennium Run, or Millennium Simulation (referring to its size [1] [2]) is a computer N-body simulation used to investigate how the distribution of matter in the Universe has evolved over time, in particular, how the observed population of galaxies was formed.
CMBFAST is a computer code, developed by Uroš Seljak and Matias Zaldarriaga (based on a Boltzmann code written by Edmund Bertschinger, Chung-Pei Ma and Paul Bode) for computing the power spectrum of the cosmic microwave background anisotropy. It is the first efficient program to do so, reducing the time taken to compute the anisotropy from ...
The Hubble eXtreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed at that time. Except for the few stars in the foreground (which are bright and easily recognizable because only they have diffraction spikes), every speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is ...
The universe's size is unknown, and it may be infinite in extent. [14] Some parts of the universe are too far away for the light emitted since the Big Bang to have had enough time to reach Earth or space-based instruments, and therefore lie outside the observable universe. In the future, light from distant galaxies will have had more time to ...
Matrioshka brains and other megastructures are a common theme in the fictional Orion's Arm universe, where they are used by superintelligences as processing nodes connected by artificial wormholes. The Dennis E. Taylor novel Heaven's River mentions building a Matrioshka brain for use with replicant and artificial intelligence.
