What was Hubble' s proposal about the universe?

Answer 1

Hubble's " proposal about the universe" is surprising considering his red shift work is claimed to be the basis of the expanding universe. Hubble's work on counting galaxies indicated a closed universe, not expanding. His view of the red shift is that it is a "hither to unrecognized principle of nature".

see this excerpt below about Hubble.

"Hubble concluded that his observed log N(m) distribution showed a large departure from Euclidean geometry, provided that the effect of redshifts on the apparent magnitudes was calculated as if the redshifts were due to a real expansion. A different correction is required if no motion exists, the redshifts then being due to an unknown cause. Hubble believed that his count data gave a more reasonable result concerning spatial curvature if the redshift correction was made assuming no recession. To the very end of his writings he maintained this position, favouring (or at the very least keeping open) the model where no true expansionexists, and therefore that the redshift "represents a hitherto unrecognized principle of nature". This viewpoint is emphasized (a) in The Realm of the Nebulae, (b)in his reply (Hubble 1937a) to the criticisms of the 1936 papers by Eddington and by McVittie, and (c) in his 1937 Rhodes Lectures published as The Observational Approach to Cosmology (Hubble 1937b). It also persists in his last published scientific paper which is an account of his Darwin Lecture (Hubble 1953)."

Answer 2

Edwin Hubble's proposal about the universe included the idea that galaxies are moving away from each other, suggesting the universe is expanding. He also observed a relationship between the distance of galaxies and their redshift, which led to the development of Hubble's Law, stating that the further a galaxy is, the faster it is moving away from us.
