cosmological constant problem

subject fact

cosmological constant problem has definition The puzzle of why the cosmological constant has a value which is either zero, or in any case roughly 120 orders of magnitude or more smaller than the value that particle theorists would expect. Particle theorists interpret the cosmological constant as a measure of the energy density of the vacuum, which they expect to be large because of the complexity of the vacuum. See vacuum. has source: Guth, A.H. 1997 The Inflationary Universe, Addison-Wesley, 2001-09-27 09:34:06.0
