expanding universe: see universe universe, totality of matter and energy in existence. The study of the origin of the universe, or cosmos, is known as cosmogony, and that of its structure and evolution, cosmology. The age of the universe depends on which theory of cosmology one accepts.

expanding universe

Current understanding of the state of the universe. It is based on the finding that all galaxies are moving away from each other. Application of general relativity to cosmology, along with the detection of redshifted light coming from galaxies outside the Milky Way Galaxy, led to the realization in the 1920s that all galaxies are receding (see Edwin Hubble). It is unknown whether the universe will expand indefinitely (open universe) or eventually collapse (closed universe) into an extremely dense, congested state, as it began, according to the big-bang model. See also Friedmann universe.

expanding universe [ik¦spand·iŋ ′yü·nə·vərs]

(astrophysics)

Explanation of the red shift observed in spectral lines from distant galaxies as due to a mutual recession of galaxies away from each other.

(relativity)

A model of the universe describing the process defined in the astronomy definition, in which the universe is nonstatic, homogeneous, and isotropic; based on Einstein's field equations with a nonvanishing cosmical constant.
