From Robert F. Beck:

Re: Something beyond visible universe detected? (Sept. 23): In my book The Special Theory of Reality, I demonstrate in Appendix 6 (freely available on my website here) that even without inflation, in an expanding universe only part of it is visible and we see nothing where it is.

The same applies in a rotating universe. All is illusion in both cases. Which is very dodgy ground for insisting that big bang theory is right!
