In Larry Niven's Known Space Universe, which is the stronger material:
 Scrith or a General Products hull?  Please explain your answer.

I would love to answer this, but unfortunately all my source materials
are locked in a Slaver Stasis Box. ;-)

Great question.

Well, I've been thinking about the question since I asked it.  I know
that scientists who read Niven's work have said that scrith must have
the tensile strength of the strong nuclear force.  This is based on
the size and angular velocity of Ringworld.  However we also know from
Niven's books that a meteorite can punch a hole in scrith.  A GP Hull,
on the other hand, is described as impenetrable (except by gravity). 
If you take this description literally, then a GP Hull is stronger.

Scrith is said to block the passage of neutrinos (40% of them,
anyway.) I may be wrong, but I don't think a General Products hull has
this property. I have not read much Niven in recent years, so I am a
bit vague on this.

Have you considered posting your question on the alt.books.larry-niven
