Black holes -- Can you chill the particles of a black hole?

Click For Summary
SUMMARY

The discussion centers on the theoretical possibility of chilling particles associated with black holes. It establishes that black holes themselves are vacuums with no particles, but Hawking radiation can be emitted from quantum black holes. The temperature of this radiation is dictated by the Bekenstein-Hawking formulas, indicating that larger black holes emit lower temperature radiation. Thus, one can indirectly lower the temperature of a black hole by increasing its mass through the addition of matter.

PREREQUISITES
  • Understanding of black hole physics
  • Familiarity with Hawking radiation
  • Knowledge of Bekenstein-Hawking formulas
  • Concept of quantum black holes
NEXT STEPS
  • Research the Bekenstein-Hawking formulas in detail
  • Explore the implications of Hawking radiation on black hole thermodynamics
  • Study methods for increasing black hole mass and its effects
  • Investigate the characteristics of quantum black holes
USEFUL FOR

Astronomers, physicists, and students interested in theoretical astrophysics and black hole thermodynamics will benefit from this discussion.

TL;DR
I have a strange question on my mind
I want to ask if you can theoretically chill the particles of a black hole and if it is possible to achieve it what will happen

A black hole is a vacuum. It has no particles.

Better to be a quark than a quack.

You can chill the particles (Hawking radiation) emitted by a quantum black hole, since after they are emitted, they are no longer in the black hole. However, you do not have any direct control of the temperature of particles emitted by a black hole. The temperature of particles emitted by a black hole is given by the Bekenstein-Hawking formulas (see Eq 1.1 in https://arxiv.org/abs/1410.1486).

The bigger a black hole is, the lower the temperature of its Hawking radiation.

So indirectly, you can lower the temperature of a black hole by making it bigger. You can make a black hole bigger by throwing stuff into it.

A classical black hole has no temperature (or can be said to be at absolute zero), and no Hawking radiation.
