How can the atoms of a back hole move if they are a compression of so much mass? Maybe black holes in the absolute zero state. Any thoughts?
UrbanXrisis said:exactly, maybe the black hole is so dense that the atoms cannot move around.
Chronos said:A black hole radiates away mass until hardly any mass remains. How much is not certain, but a good guess is around a Planck mass [~10E-08kg]. At that point it gives off one last tiny burst of radiation and evaporates althogether - at least in theory. This takes a very long time so don't expect to see any photos anytime soon. Hawking's concept is interesting, though highly speculative. The universe more strongly resembles a time reversed black hole: it began as a singularity that rapidly expanded to enormous size and has continued to expand since.
Is this not a contradiction?Phobos said:Nothing can radiate beyond the event horizon (don't ask me what's going on within the event horizon!)
UrbanXrisis said:How does a black hole sacrifices mass in order to power the radiation? Nothing can excape a black hole, how does it supply mass in the form of energy? If you're talking about Hawking Radiation, that happens outside of the actualy black hole and has nothing to do with the black hole itself. How would the black hole itself actually lose mass?
I'm talking about absolute zero. We DONT know what happens when we hit absolute zero, just like we don't know what will happen when we reach a singularity. I'm saying that they might be related in that absolute zero is not a temperature but is the coldest and hottest whatever that at the curretn time is indescribable. What state would we reach when atoms are in absolute zero state? Not a solid, liquid, gas, plasma, bose-einstein condensate, fermionic condensate, quark-gluon plasma, but something beyond. Maybe the "atoms" in a singularity are so compact that they stop moving due to the immense force of gravity. Which is called absloute zeroPhobos said:Like DB said, modern physics can't describe the singularity itself very well. But, as a point, there are no atoms there. Anyway, how can the singularity have temperature?
We don't know anything and I wasn't trying to relate temperature into any of this, just because I said "Absolute Zero." I was trying to imply the obscure relationship between the two. I take back my thought because of what Chronos said.UrbanXrisis said:I'm saying that they might be related in that absolute zero is not a temperature but is the coldest and hottest whatever that at the curretn time is indescribable.
This tells me that in a black hole, atoms are "disassembled" and ripped apart. But the absolute zero state, I considered that the atoms are still in tack and have not been torn into quarks.Chronos said:atoms are disassembled into elementary particles [protons, neutrons, electrons], particles are torn to pieces, and the pieces themselves [e.g., quarks] are presumable mangled into God knows what kind of exotic smear of weidness.

Chronos said:Indulge me to add this about the temperature of a black hole. A black hole does have a temperature. Hawking radiation is the temperature of a black hole. It is inversely proportionate to mass. Massive black holes are extremely frigid, but are always at a temperature above absolute zero.
A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape from it. It is formed when a massive star dies and its core collapses under its own gravity.
Black holes compress mass through their intense gravitational pull. As matter falls into a black hole, it is squeezed and compressed to a point of infinite density known as the singularity.
Once something crosses the event horizon of a black hole, it cannot escape. This is because the escape velocity, or the speed required to break free from the gravitational pull, is greater than the speed of light.
Near a black hole, the intense gravitational pull causes time and space to become distorted. This phenomenon is known as gravitational time dilation and it means that time passes slower near a black hole compared to farther away from it.
Absolute zero is the theoretical temperature at which all molecular motion stops. It is closely related to black holes because the intense gravitational pull at the singularity causes the temperature to approach absolute zero, making it the coldest place in the universe.
