This is not technically for debate, but for clarification and definition.www.nasa.gov/worldbook/blackhole_worldbook.htmlWhat better place to look up a black hole than at the National Air and Space Administration? Black holes result when a star at least three times as massive as our Sun dies and collapses. The resulting masses, black holes, are so dense that some are believed to be smaller than an average atom's nucleus. The gravitational pull of black holes get stronger as you approach the surface of the black hole, and eventually there is a point in space around the black hole called the event horizon where gravity is infinitely strong. Anything that reaches the event horizon, even light, is pulled in without any hope of escape. Black holes, because they absorb light, cannot be seen except by observation of nearby masses or by observation of immense x-ray emission. teachspacescience.org/graphics/pdf/10001043.pdfThis is based off NASA information and is also a reliable source. It is longer, but it has more information and presents it in a more reader-friendly manner. Take a look at it. There is even a glossary of certain terms, such as event horizon (distance from center of black hole where escape velocity is equivalent to the speed of light).

Thats helpful for other people, but i already knew all of that

Don't forget the forms of singularities!

Some people are incredibly ignorant os scince. Natasha Bedingfield, are you General Veers?

Yes, I am General Veers. I have an apparent obsession with her songs just about as much as I do with the AT-ATs in Star Wars...
...but enough with my choice after the name-epidemic, this is Serious Debate, and this thread is for defining and explaining what a true black hole is...

The PDF already looks like crap. Black holes are finite.

Where does it say to the contrary? I must have missed that despite reading the entire thing...

Finite black holes? Whoever said they were infinite?
|

Post by The Dark Master on Feb 20, 2009 9:00:08 GMT -5
as in infinite size, or an infinite density in the singularity?

The only mention of infinity I found was in context with the gravitational field's strength at the event horizon, when the escape velocity is the speed of light.

There is no singularity. There is not information paradox. There is not 'outside' which matter goes to.
PDF is complete bull, and NASA is complete bull. It SOUNDS reasonable (coming from them), but if they bothered THINKING ABOUT IT.

Bother about thinking about it? SM, your becoming ignorant. The greatest scientific minds of this day and age have thought about it for hours on end. Dont expect yourself to be right all the time.

There is only one thing that can escape a black hole. Particles of gravity called gravitrons. I dont know how exactly they work but they are responsable for gravity. And isnt tehere a movie called event horizon i heard it sux has anyone here seen it?
