| 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 (...) (21 years ago, 11-Aug-03, to lugnet.off-topic.geek, lugnet.space)

Carl Sagan tossed that out as a possibility in Contact (...) (21 years ago, 11-Aug-03, to lugnet.off-topic.geek)

| (...) If it's a rotating black hole (and just about everything in the universe rotates), then the vacuum solution to the Einstein Field equations gives a flat ring shaped singularity rather than a point. (21 years ago, 12-Aug-03, to lugnet.off-topic.geek)

| 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)

| (...) The "matter" a black hole gives off is Xrays. The constant streamout of Xrays is what will, in about 10e60 years (what? no exponent in FTX?) cause black holes to start exploding. At this time, exploding black holes will be the only source of (...) (21 years ago, 12-Aug-03, to lugnet.off-topic.geek, FTX)

In the typical diagram, the x and y axis describe area, while the z axis (up and down) describes graviational warping of spacetime. (...) (21 years ago, 15-Aug-03, to lugnet.off-topic.geek, FTX)

| (...) Hate to be a bummer, but the only matter black holes "emit" would be Hawking Radiation, and scientists are unsure about what will happen when a black hole stops. X-ray are a type of light, and since, by definition, black holes don't emit (...) (21 years ago, 15-Aug-03, to lugnet.off-topic.geek, FTX)
