The thing is the doppler shift interpretation is disputed, as are many of the various things "proving" big bang theory. Anyone in the field that questions/disputes BBT cosmology is drummed out, ignored, defunded etc (same treatment as anyone against AGW in climatology).
I personally don't think it makes a damn bit of sense that everything suddenly formed out of nothing in a REALLY REALLY YUGE explosion, and that the universe simply is (with parts of it coming and going like anything else).
