big crunchis a kind of cosmology theory2001-09-27 09:34:01.0
has definition The state of extremely high density and temperature into which a closed universe will recollapse in the distant future.has source: Hawley, J.F., Halcomb, K.H. 1998 Foundations of Modern Cosmology, Oxford University Press, 2001-09-27 09:34:01.0
has definition If the universe has a mass density exceeding the critical mass density, then gravity will eventually reverse the expansion, causing the universe to recollapse into what is often called the big crunch. See also closed universe.has source: Guth, A.H. 1997 The Inflationary Universe, Addison-Wesley, 2001-09-27 09:34:01.0
has definition One hypothesized future for the universe in which the current expansion stops, reverses, and results in all space and all matter collapsing together; a reversal of the big bang.has source: Greene, B. 1999 The Elegant Universe, W.W. Norton and Co., New York, 2001-09-27 09:34:01.0
