Gravity affect on the motion of atoms ?

Click For Summary
SUMMARY

The discussion centers on the effects of gravity near supermassive black holes and the implications for atomic movement. It is established that at the core of a black hole, known as a singularity, traditional atomic structures do not exist, and thus concepts like temperature and entropy become meaningless. The conversation highlights that while a black hole emits Hawking radiation, the singularity itself does not possess temperature. Additionally, the light cone structure within a black hole prevents information from escaping, further complicating our understanding of entropy and temperature in these extreme environments.

I was wondering if the run away gravity in a super massive black hole could cause a lock up of sorts, and stop (nearly) all atomic movement? Packing the matter at it's core so tightly, that it would paralyze it at an atomic level. Could this possibly mean that near the center of these monsters, it could actually be...cold?
Bringing things into the strange world of quantum mechanics and making the strange quantum states of mater and particles possible?

There is no "packing" at the core. Assuming the center is a singularity (=what General Relativity predicts) there are no atoms, or even individual particles any more. That also means the singularity itself does not have a temperature. The black hole as a whole object has one due to Hawking radiation, but that is a completely different thing.

If you are close to the event horizon of a black hole, but not falling in, all incoming light will be extremely blueshifted and will appear very hot to you.
If you are inside, you have to fall in, but blue-shifting can still happen.
 
Firstly, atomic lattice structure is not compatible with the light cone structure theoretically predicted inside a black hole, and is thus forbidden by principle of causality. (Unless some new theory breaks this, such as a tesseract bookshelf at the singularity:-p)

Secondly, the light cone structure dictates that information from the singularity is never transmitted radially outwards and thus no observer away from singularity could obtain any information about it. Without information, the notion of entropy is meaningless and so is temperature.

*However, black hole does have entropy. This is a mostly unresolved problem and people like Leonard Susskind proposed holographic principle to cope with it. Although I am no expert on holograms, I would assume that does not contain any information on the singularity itself nevertheless. But this is too far beyond the topic of this thread.
 
Are you familiar with neutron stars?
