This is incorrect. Please check the many explanations in
this Q&A thread

we look, the more 'distorted' must be our view as compared to the CU
(the universe as it is now).

I'm not sure why you think "senior cosmologists" are unaware of this. If you check out
this page, I believe you'll realize that they understand the situation much more completely than you.

I would say the CU is likely to look much like the OU. What is your reason for thinking differently?

Again, incorrect. Look at
that second link again. The little animation is especially illuminating.
