Did Hubble opine that the universe was expanding?

AI Thread Summary
Hubble's observations indicated that galaxies were moving away from each other, showing a correlation between distance and redshift, but he did not explicitly state that this meant the universe was expanding. Instead, he and Humason emphasized the empirical nature of their findings and left the interpretation to others. Hubble was cautious about concluding that his data suggested an expanding universe, often questioning but not entirely dismissing that idea throughout his life. The discussion highlights the distinction between Hubble's observations and the later interpretations that led to the concept of an expanding universe. Ultimately, Hubble's reluctance to assert an expanding universe reflects the complexity of interpreting early astronomical data.

When Hubble published that the galaxies were moving away from each other, the further away the greater redshift and the greater separation velocity, was he saying that space itself was expanding, on the basis of Einstein's general theory, or was he assuming a more or less fixed space, with everything in it retreating from everything else? In other words, did he come up with the idea of an expanding universe - as opposed to a fixed framework within which all the players were flying apart - or did someone else draw that conclusion as a result of his observations?

Hubble and Humason did not say that redshifted “nebulae” were receding from us. They left the interpretation of their data to others. See this quotation:

“Mr. Humason and I are both deeply sensible of your gracious appreciation of the papers on velocities and distances of nebulae. We use the term ‘apparent’ velocities to emphasize the empirical features of the correlation. The interpretation, we feel, should be left to you and the very few others who are competent to discuss the matter with authority.”

One more example of historical evidence, written by Hubble himself, is here:

Yes, Hubble was reluctant to conclude his redshift studies suggested the universe was expanding. He questioned, but, never entirely rejected that interpretation for most of his life.
 
'Opine'? Man, somebody must have gotten a thesaurus for Christmas...

Abstract The Event Horizon Telescope (EHT) has significantly advanced our ability to study black holes, achieving unprecedented spatial resolution and revealing horizon-scale structures. Notably, these observations feature a distinctive dark shadow—primarily arising from faint jet emissions—surrounded by a bright photon ring. Anticipated upgrades of the EHT promise substantial improvements in dynamic range, enabling deeper exploration of low-background regions, particularly the inner shadow...
https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.
