Quote: "Well, theoretically a black hole isnt a hole, it is indeed a super-compressed point of particles with extreme density and mass. The blackness around it is cause by the fact that no light can escape from within a certain radius of it."
We know they exist, and that they are the result of a nova.
Also known is that they are a similar phenominom to a quasar or pulsar.
A current popular theory is that the materials that make up each star often varies causing the different results from the nova. The black hole itself is believed to be caused by a super-heavy atomic core, which because of the gravity effect created causes the light to "disappear" when the reality is what is happening is thought to be a funnel effect with a bag. The core pulls in all material condensing it until it eventually errupts with a similar effect to a super nova causing all of this star making materials to be throw over hundreds of light-yers; basically ceating a star nursery.
How this differs to a pulsar is that the materials from the pulsar generally retain their magnetisphere causing the poles to change so to speak. This means that while matter is still sucked in from almost every direction (due to the gravitational pull) there are basically two exit streams as well that is constantly throwing out all of this material (including light).
The quasar is different again, along the same lines that it sucks in matter; but at the same time it reaches a critical mass very quickly causing a micro-nova periodically.
Again these are the current commonly accepted theory on how Singularities are formed and behave.
