I found out something I really should have picked up on years ago...
I thought the Steady State Model went for a non expanding universe but it has in common with the Big Bang Model expansion...it seems it is the Static universe model that is without expansion.
And another unteresting aspect Hubble would not publicly say he favoured an expanding universe model which is rather funny given it was his onservations that were used to promote an expanding universe.
