| 释义 |
}} 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.{{cn|date=January 2016}} Pair separation histogramsCosmic crystallographers use cosmic separation histograms to infer characteristics of the universe. Large spikes are expected to appear if the universe is not simply connected. References{{Portal bar|Physics|Cosmology|Space}} 1 : Physical cosmology |
