n.
a model of the universe, based on observed redshifts of distant galaxies, in which the galaxies are receding from each other at a speed proportional to their separation.
[1930–35]

ex·pand·ing universe

(ĭk-spăn′dĭng)
A model of the universe in which the volume of the universe is expanding. It is based on the idea that the red shift in light from distant galaxies is evidence that all galaxies are moving away from one another. See Notes at big bang, Doppler effect.
