Perhaps there is no expansion, at least not due to a big bang which never happened. About 20 years ago, Halton Arp and John Bahcall published a debate in The Redshift Controversy, presenting both sides of the argument.
The debate presented Halton Arps side of the arguement. 
The text says that the debate presented both of their arguments, so my statement that the debate presented Halton Arps side of the argument is definitely correct, as well as my next statement which was "The debate presented John Bahcalls side of the argument." both are definitely correct.
