something overmissed

now I didn't read the book
but from movie fan view i did bit thinkering :D

the trickery behind spaceship and black hole
-
while the crew (seems) to kill each other as they supposedly
realised what sphere offered

but what if last survivor, even if wounded also made simmiliar thing
as it was et the end of movie

he wished to destroy the sphere PERMANENT
and the only thing what is known about space, is that black holes
simply destroy everything and anything...

so what if last survivor wished to create a black hole - on purpose
and to fly the ship in, again on purpose, not only to destroy it
but to prevent anyone in future to get hold of the sphere

and incidently black hole kicked him in past,

the whole debate in movie about "Unknown Event" for Black hole
doesn't have to apply to "computer didn't know"
but rather how computer can't determine what singularity was
since error message appeared when they crossed in the black hole...
