Discussion Overview

The discussion centers around the mechanisms by which black holes radiate energy, specifically focusing on the geometry of this radiation. Participants explore theoretical frameworks and current understanding related to black hole radiation, including Hawking radiation and other potential processes.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the geometry of radiation emitted by black holes, asking whether it is planar, polar, or follows another pattern.
  • Another participant references Hawking radiation, describing it as a result of virtual particle production near the event horizon, where one particle may fall into the black hole while another escapes.
  • There is mention of charged particles potentially radiating as they are accelerated toward the black hole, suggesting additional mechanisms of radiation beyond Hawking radiation.
  • A later reply seeks clarification on current theories regarding the geometric aspects of how radiation is emitted from black holes, indicating a desire for more detailed theoretical insights.

Areas of Agreement / Disagreement

Participants express interest in the topic but do not reach a consensus on the specific geometric nature of black hole radiation or the completeness of current theories.

Contextual Notes

The discussion reflects uncertainty regarding the current state of theories on black hole radiation geometry and does not resolve the complexities involved in understanding these processes.

Hi, I was wondering how black hole's radiate energy and to be specific what the geometry of this radiation is. Can they radiate it planar, polar like a gamma ray burster, or something else? I'm not sure how far astrophysicists have gotten in terms of the theory of this, so please include all the ways we 'think' they radiate energy that you know of.

Cheers.

Hawking proposed 'Hawking' radiation, which I think is due to virtual particle production (limited by uncertainty principle) very near the event horizon, where one virtual particle falls into (or escapes from) the black hole. It is possible that charged particles approaching the event horizon from the outside could radiate as they are accelerated toward the black hole.
 
Where can I get clear explanations of how s-process and r-process works in stars. Diagrams and examples how neutron capture bumps elements up the period table. Which elements are created by either process.

Marty, I don't see how your post follows.

Applogies. A slip of the finger on keyboard. This is meant to be a new topic - I'll repost.

Yes. I'm aware of Hawking's theory. I'm more interested in knowing current theories on how the radiation is actually radiated geometrically from the black holes. I'm not sure if any current theories attempt to cover this process so I was hoping an expert in the field might offer some ideas.
