| Lemaã®Tre Universe |
A model of the universe that begins with a Big Bang, has a static phase and then expands indefinitely. It is named after Georges Lemaître 1894-1966, who in 1927 published a major work on the expansion of the universe. He was the first to advocate expansion from a primeval atom, while Einstein was still propounding the merits of a static universe.
