Each work unit represents a single Universe. When the work unit is requested by a participating computer, this computer simulates this Universe from the Big Bang until today. The result of this simulation is a list of observable properties of this Universe. This result is then sent back and archived at the Cosmology@Home server.
A wide field view of outer space as seen from Earth's surface at night. The interplanetary dust cloud is visible as the horizontal band of zodiacal light, including the false dawn [29] (edges) and gegenschein (center), which is visually crossed by the Milky Way. Outer space is the closest known approximation to a perfect vacuum.
Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. "Free space" means air, outer space, vacuum, or something similar. This contrasts with using solids such as optical fiber cable.
Outer space (or simply space) is the expanse that exists beyond Earth's atmosphere and between celestial bodies. It contains ultra-low levels of particle densities , constituting a near-perfect vacuum of predominantly hydrogen and helium plasma , permeated by electromagnetic radiation , cosmic rays , neutrinos , magnetic fields and dust .
Cosmic microwave background radiation (CMBR) from outer space is also a form of cosmic noise. CMBR is thought to be a relic of the Big Bang, and pervades the space almost homogeneously over the entire celestial sphere. The bandwidth of the CMBR is wide, though the peak is in the microwave range.
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.

1983 – Computer simulations sophisticated enough to provide relatively reliable results of growth and evolution of the large-scale structure emerged and yielded insight on key features of the large-scale galaxy distribution. [17] [18] 1985 – Details of the supercluster and void structure of the Perseus–Pisces region were surveyed. [19]
