There are other ways to get to a similar result. I'm poking around in www.ipod.org.uk/reality/, web pages of Andrew Thomas (author of a series of books titled "Hidden in Plain Sight"), recalling that he created a model that supposedly does similar, by making a modification to the law of gravity. The modification only works on objects that are massive compared with their volume (black holes; galaxies).
I can't find it in a google search, would have to find the reference in the book - anyway, Dr. Thomas posits no big bang, but a sort of "big pushout," and that everything strives for a surface area commensurate with its mass. For a black hole, that area is the event horizon.
Thanks for the links.
An honest question;
Can the Universe exist without expansion ?
I’m not prepared to support a “Steady State” model, however there was recently some data that may call into question the expansion model.
