Cosmic crystallography
![]() | This article needs additional citations for verification. (January 2015) |
Cosmic crystallography is a technique used in physics and astronomy to determine the possible topology of the universe (e.g. a torus, 3-sphere, etc.). Astronomers observe sources of high redshift and look for repeating patterns that may indicate the connection of edges.[1]
Pair separation histograms[]
Cosmic crystallographers use cosmic separation histograms to infer characteristics of the universe. Large spikes are expected to appear if the universe is not simply connected.
