Expanding universe and Big Bang Theory go hand-in-hand. There are multiple independent observations besides the red shift that make it nearly certain there had to be a BBT event to explain what we see. The universe is too hot, chaotic and clumpy for there not to have been a massive explosion to kick it all into motion. Since there is good confidence BBT happened, transitioning from that event to a steady-state non-expanding universe would require some sort of mechanism to slow then freeze the expansion. Not aware of any support for that model.
- fanf2 2y agoThe name “big bang” was a pejorative epithet coined by Fred Hoyle, who believed in a steady-state universe that was expanding (as Hubble had argued convincingly) but had some hypothetical mechanism for creating galaxies, such that the universe could have an unbounded past and future. So, historically, they did not go hand-in-hand. https://en.wikipedia.org/wiki/Fred_Hoyle#Rejection_of_the_Big_Bang https://en.wikipedia.org/wiki/Fred_Hoyle#Rejection_of_the_Bi...
- while_true_ 2y agoTrue, but with the BBT-affirming discovery of the cosmic microwave background in 1965 they've been hand-in-hand ever since.
