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.
Lemaître employed blatant attention getting techniques, like using the name of one of his famous competitors in the opening sentence of his papers.
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.
Yet many of the most extensive scientific observations ever made suggest otherwise, and they don't give a ringing endorsement to the Copernican principle either.
The first couple items in this list come from the highly sophisticated maps of the (shadowless) CMB (cosmic microwave background) and subsequent analysis.
[Unlike Einstein's (& Newton's) difficulty in explaining why the universe doesn't gravitationally implode, Friedmann made an interpretation of general relativity that indicated an expanding universe.For a creationist and a secular explanation of this problem, see creation.com's report on the Discovery Channel's How the Universe Works, and see this Fermilab antimatter video: Yet even secular science authorities have begun objecting to the systematic misattribution, and hence, post-dating, of the the claim of expansion.Expansion was not a "prediction" of the 1931 big bang theory; it was a 1920s interpretation of both Einstein's equations and red-shift data.- Hubble wrote to de Sitter in 1930, "I consider the velocity-distance relation [i.e., "Hubble's Law"], its formulation, testing and confirmation, as a Mount Wilson [i.e., Hubble] contribution and I am deeply concerned in its recognition as such." Clearly.- The astronomy establishment, Nasa, et al., psychoanalyzes Lemaître and claims that he was humble and did not desire "establishing priority for his original discovery." So perhaps RSR could be forgiven for trying our own hand at psychoanalysis.
