Imagine the Universe!

Movie (2.4 MB)


The is a computer simulation illustrating the formation of galaxy clusters and large-scale filaments in a model of the universe which includes Cold Dark Matter and dark energy. The frames show the evolution of structures in a 43 million parsecs (or 140 million light years) box from redshift of z=30 (shortly after the Big Bang) to the present. Initially all the particles are distributed throughout the box. They quickly start clumping together.

Imagine the Universe is a service of the High Energy Astrophysics Science Archive Research Center (HEASARC), Dr. Alan Smale (Director), within the Astrophysics Science Division (ASD) at NASA's Goddard Space Flight Center.
