As widely documented and shown below, published theoretical and observational considerations that pre-dated Hubble suggested that many galaxies are receding.] The universe was expanding after all, just as General Relativity originally predicted! GR can support a static, contracting, or expanding universe.] ...In other words, the Hubble law is just what one would expect for a homogeneous expanding universe, as predicted [retrodicted] by the Big Bang theory.What Lemaître sought were solutions to [Einstein's] field equations that would avoid "Einstein's static universe... (Eddington in 1931 estimated the universe originally at between a billion and 1.2 billion light-years in radius before it began expanding and later that same year Lemaître wrote in Monthly Notices on how, "the expansion of may be started..." (Note, this explicitly is NOT a big bang origin of the universe but the start of an expansion of a universe already in existence.) - 1929 Edwin Hubble: A relation between distance and radial velocity among extra-galactic nebulae, which paper included the "Hubble Law" [called that because Hubble failed to attribute it as Lemaître's Law].- 1931 Arthur Eddington: Mentioning in passing Lemaître and the growing belief in an expanding universe, Eddington suggests: From the astronomical data it appears that the original radius of space [i.e., the universe] was 1200 million light years. At that radius the mutual attraction of the matter in the world [cosmos] was just sufficient to hold it together and check the tendency to expand. An expansion [from an initially static universe] began, slow at first; but the more widely the matter was scattered the less able was the mutual gravitation to check the expansion.
Then in a later paper, Lemaître himself claims credit for this discovery by directly pointing out: "The title of my note [1927 paper] leaves no doubt about my intentions..." - Hubble and the astronomy establishment have allegedly been "cleared" from the charge of censorship, however, the Royal Astronomical Society invited Lemaître to translate for publication paragraphs 1 to 72 of his 1927 paper, with paragraph 73 containing his discovery of the "Hubble" Law.
We do not know the radius of space to-day, but I should estimate that it is not less than ten times the original radius.
[square-bracket comments and emphasis added] single atom] had not yet been proposed.
- The "It is still widely held that in 1929 Edwin Hubble discovered the expanding Universe and that this discovery was based on his extended observations of redshifts in spiral nebulae. There is little excuse for this, since there exists sufficient well-supported evidence about the circumstances of the discovery.
The circumstances have been well documented even recently with the publication of two books: Bartusiak (2010), Nussbaumer & Bieri (2009).
