ylem | has definition The word used by Gamow and his collaborators for the primordial material of the Big Bang. In most of his work Gamow assumed that the ylem consisted entirely of neutrons. In inflationary cosmology, the role of the ylem is played by the false vacuum. | ![has source: Guth, A.H. 1997 The Inflationary Universe, Addison-Wesley, 2001-09-27 09:28:32.0 has source: Guth, A.H. 1997 The Inflationary Universe, Addison-Wesley, 2001-09-27 09:28:32.0](facet.gif) |
has definition Primordial state of matter - neutrons and their decay products (protons and electrons) - before the Big Bang. The term was taken from Aristotle and used for the α-β-γ theory. | ![has source: Abbot, D. 1984 Astronomers, Peter Bedrick Books, New York, 2001-09-27 09:28:32.0 has source: Abbot, D. 1984 Astronomers, Peter Bedrick Books, New York, 2001-09-27 09:28:32.0](facet.gif) |
