I have began to study these. They are very interesting. The idea of a "point" having that much influence is fascinating.

Originally posted by FabianFnasThe idea they keep pushing is infinite density, I think that is just a sign we don't know what we are talking about yet.

I have a few problems with black hole theory.
The first one being, if energy can neither be created nor destroyed, any heat created from the collision of particles would not be able to escape the event horizon and would just accumulate within the black hole.
The second, if the mass is compacted to a point then there is no free movement between electron ...[text shortened]... re of neither hot or cold.
Or am I just completely mad and worthy of the mockery of my peers?
Originally posted by FabianFnasI would go with that.
Let's say for the discussion that the density is not infinite...
Matter of it's usual form, like electrons and ions doesn not exist in this extremely high density.
If we go to the matter in the deeper regions, but not centre, of a neutron star, there are no electrons at all, nor protons. Everything are neutrons. So in this sense a neutron star is one ...[text shortened]... inst the string theory's not yet discovered properties.
But again - what do I know...?

To keep it simple, it all boils down to magnetism and what is it?
super string=some sort of coagulation of varying degrees of magnetic flux?
I think the simple experiment of water in a cup, evaporating due to the heat of the sun holds the answer to the soup of black holes.

Originally posted by TeraMicro Black Holes are produced naturally when cosmic high energy particles strike our atmosphere, and artificially when high energietic particles are smashed inot one onother in the Cern laboratory in Geneva (and other large accelerators).
At the event horizon there are the same spontaneous creation of particles and antiparticles as in the remainder of space. But once in a while these antiparticles and particles happen to pass the way so that the antiparticles move inside the black hole and the particles of course move the opposite direction. Thus in effect the black hole is "radiating" a certain ...[text shortened]... , I don't know much about that but it struck me as funny. Don't mess with thermodynamics :p
Originally posted by FabianFnasThinking about those microholes, if our universe is the other side of a black hole, what about these micro dudes?
Micro Black Holes are produced naturally when cosmic high energy particles strike our atmosphere, and artificially when high energietic particles are smashed inot one onother in the Cern laboratory in Geneva (and other large accelerators).
Micro Black Holes disappear quite quickly (in a matter of microseconds or less), due to Hawking radiation (describ ...[text shortened]... the latest posting). So the time of 10^55 years, well, it depends of the mass of the black hole.

Black holes have a size (the radius of the event horizon), mass etc. What makes them so special is the fact that they bend space so much that nothing can escape them - not even light. However, energy can escape them via quantum processes.
The physics is a little ...[text shortened]... different from outside except for the extremes involved.
There are no infinities involved!
