The nonsense of an expanding universe (i.e. big bang religion) relies heavily on the Hubble law which relates the redshift of distant galaxies to their distance, and very simply this has been a distortion of a great man’s work by believing that the full redshift is all due to the Doppler effect. Geez they’re bloody drips to blindly believe that one.
The redshift of distant galaxies is due at least in part to the effect of intergalactic gravitational fields on light and of course a rotating body warps and twists the "fabric" of “space” thus altering photons and their spectrum. There are other reasons for a red shift too but distant red galaxies are not ALL receding from us any more than nearby galaxies.
This means that there is no reason to believe that the universe is expanding, and therefore no reason to believe that there ever was a Big Bang.
