Is there an EU/PC estimation of the size of the known universe?
I would assume infinite as only BBT has a "size".
Nah, I think what Allynh says makes more sense:

The fun thing about the Small Universe concept -- 300m light years across, a Poincare sphere -- is that it appears infinite from the inside. That no matter where you look you will see galaxies in the far distance.
Those galaxies we see are simply fossil images, and we need to find a way to identify the different images.
- Think of standing inside a mirrored cube, ten feet across. No matter where you look you see yourself extending out for miles.
With the Webb telescope we should "start" to see stigmata of that fossil light, and distortions caused by us being in a closed space.
We are only now putting technology in space that can begin to answer these questions.
A century ago they thought that space was randomly filled with stars, they had no concept of "galaxies". When Palomar started showing that "nebulas" were actually vast galaxies filled with stars, they went through a profound shock that is still unresolved.
We are going to need multiple Webb telescopes working together to form a larger telescope that can see farther and wider before we can actually see what is out there.
