I wonder how much you'll have to deny in order to really have a
good argument against that 92 +/- billion light year theory. And
let's not get hung up on the word "theory." Remember, universal
gravitation is also a theory.

If you accept the 13.x billion year time period since the Big Bang
then insisting on the radius of the universe being only 13.x
billion light years is going to require some interesting theories
from you. Has the farthest stuff we can see been stationary for all
this time? If not, then calculating the ~92 +/- billion light year
diameter of the universe is simple geometry.
