A Black Hole is supposed to be a collapsed neutron (type?) star, right? So
then, why is a Black Hole always depicted as an infinite toilet-flush? I can
understand that the "matter disc" forms into a disc because of gravity, like the
rings of a planet, but shouldn't the actual
whatever-is-at-the-heart-of-a-black-hole be an infinitely small pinpoint?
I'd attribute this to popular myth, except that even NASA seems to show the
"infinite toilet-flush" as the shape of a black hole.

| No, Stefan, a Black Hole is a collapsed super-giant star. If a star is like our sun it will grow, then shrink to a white dwarf. If it were some bigger, it would collapse to a neutron star (where a spoonful weighs millions of tons), and if it were a (...) (21 years ago, 12-Aug-03, to lugnet.off-topic.geek)
