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?
