Why does hawking radiation in black holes slowly increase?

Click For Summary

Discussion Overview

The discussion revolves around the concept of Hawking radiation in black holes, specifically addressing the nature of particles involved, their interactions with black holes, and the implications of these processes on black hole energy loss. The scope includes theoretical aspects and conceptual clarifications related to black hole physics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions the nature of 'particles' that appear with negative mass counterparts and their rapid disappearance, seeking clarity on their role in energy loss from black holes.
  • The same participant speculates whether negative mass particles act as "anti-energy" that absorbs energy from within the black hole.
  • The participant expresses confusion about why the rate of Hawking radiation increases as black holes shrink, suggesting that a smaller surface area would intuitively slow down the process.
  • Another participant asserts that the initial description of the process is incorrect, referencing Hawking's original papers and suggesting that the explanation provided is merely a conceptual tool rather than an accurate depiction of the phenomenon.
  • A repeated assertion emphasizes the need for a more accurate explanation of Hawking radiation beyond commonly found descriptions.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are competing views on the nature of particles involved in Hawking radiation and the accuracy of the explanations provided. The discussion remains unresolved regarding the correct interpretation of these processes.

Contextual Notes

There are limitations in the understanding of the mechanisms behind Hawking radiation, particularly regarding the definitions of negative mass and its implications. The discussion highlights unresolved questions about the relationship between black hole size and the rate of radiation.

First, what are these 'particles' that appear with their negative mass counterpart and suddenly disappear very quickly and why do they do that?

Now, I know the positive mass ones are allowed to escape the event horizon while the negative mass doesn't, thus fall into the black hole, but how does the negative mass one cause the black hole to lose energy?
is the negative mass particle just an "anti-energy" that sucks in whatever is inside the black hole?

and most importantly, why does this get faster and faster as the black hole becomes smaller? All I can see is that there is less surface area for the black hole to pull in and leave out these things and thus it would slow down.

Thank you!

The picture you describe is not what happens. Hawking says so in his paper. It's a way to get comfortable with the idea, but you cannot draw conclusions from it.

Everywhere I've looked they give this same similar explanation. Where can I find a better explanation of what actually happens?
