Because the “edge” of our universe where we see the CMB is not a point in space we are viewing in real time that is currently emitting the CMB.

That edge is a sphere in space that was far enough away when the CMB was emitted in the past that we only see the light from it now.



Yep, but this sphere must have radius up to 14Bly, to be part of BB.


The observable universe has a diameter of about 47 billion light years!

Then we need to move the time of BB to 47/2 = 23.6By. Moreover, we should do that every time when we improve our telescopes.


Correction... I meant radius of 47 billion light years. It's about 94 billion light years across!
