[Sergei SOLOVIEV]

In fact, while "artistic illusion" in BoTNS (or coherence of details) is 
extraordinary,
it is not perfect, and I don't think we should try to get all 
"scientific" consequences.

One illustration: it is said that the flyer of the autarch is naturally 
afloat by
anti-gravity, and that it is created by some amount of antimatter. 
(Explanation
that the autarch gives to Severian. It is kept by ropes before flight.)
Does repulsive or attractive
force exist between matter and antimatter is not clear
for our science (I think the experiments concerning the reaction of 
antimatter
to gravitational field are only planned). Let us take this as an assumption
(author's right). But... But antimatter violently reacts
with matter. Of course inside the flyer it may be kept isolated (for
example, by magnetic fields etc.). But after the flyer is hit, it fells. 
What
happened with antimatter and buoyancy? If it was lost, where was the 
explosion?
(Many megatons at least.)

I think, the same is with this idea of black hole inside the sun.
(Description is merely not correct.)
Black hole sucks violently matter into it. Its mass grows, its sucks
more quickly. The process is exponentially accelerating. The idea
of slow death of the sun doesn't work. (In fact, core collapse in
supernovae takes fractions of seconds.)

But maybe Gene Wolfe didn't verify it scientifically.
