So the universe is infinite and steady state and the red shift is an illusion, merrily, merrily, merrily, merrily ... Just kidding. Actually the infinite part and the "no curved spacetime" part are appealing. I don't understand how you make the leap from expansion to steady state even though I do understand your analogy about gravity diminishing over distance and the wavelength increasing as a result; it just doesn't seem to be significant enough to pooh pooh expansion itself. And there are so many good reasons to believe there really is expansion.

You might have said it or at least intimated that the universe has always existed and appealed to logic and BBT flaws. I like that. But there are problems with a steady state theory that requires expansion and red shift to be wrong. And what do you replace GTR and curved spacetime with? What makes gravity work if space isn't warped by mass. I agree with you but I wonder if you have an alternative?
