Electron falls into black hole. what happens.

Click For Summary

Discussion Overview

The discussion revolves around the behavior of an electron as it falls into a black hole, specifically focusing on the energy dynamics, radiation emission, and the effects of curved spacetime on the electron's properties. The scope includes theoretical considerations and conceptual clarifications related to particle physics and general relativity.

Discussion Character

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

Main Points Raised

  • One participant questions whether the electron will lose all its energy by the time it reaches the event horizon or if it will have sufficient energy to produce a particle shower.
  • Another participant suggests that understanding the source of the electron's energy and the conditions for particle showers could help address the initial question.
  • A participant expresses curiosity about the effects of curved spacetime on the electron's behavior.
  • One response claims that the electron does not experience anything special due to curved spacetime, but notes that it would alter the wave-function and emphasizes the importance of specifying the observer in discussions of relativity.
  • The same participant invites further clarification on what specific phenomena related to the electron are of interest.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are differing views on the implications of curved spacetime for the electron and the conditions under which particle showers may occur.

Contextual Notes

There are limitations regarding the assumptions made about energy sources, the nature of particle showers, and the specifics of observation in relativistic contexts that remain unresolved.

the electron falls and emits radiation. will it lose all it's energy by the time it reaches the event horizon or will it have enough (>2m) to produce a particle shower? Will other things happen?

You can probably work that our by realizing where the electron got all that energy from in the first place and how particle showers usually occur.
 
you are right, didn't think there. So what happens then? What effect does the curved spacetime have on the electron?
 
Nothing special - the electron does not care about curved space-time.
It'd alter the wave-function though... whenever you want to ask questions about relativity you have to say who is doing the observing and so on. When you want to do this for fundamental particles you have to talk about how the observing is happening. Otherwise everything is so general you won't get useful answers.

Perhaps if you were to explain what it is about an electron that leads you to suspect that something special may happen, or what sort of phenomina you are interested in?
