Variance of mass inside a black hole

Click For Summary

Discussion Overview

The discussion revolves around the calculation of the variance of mass released when a particle transitions between energy levels inside a black hole. Participants explore the theoretical implications and challenges of this topic, which intersects quantum mechanics and general relativity.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant expresses uncertainty about the feasibility of calculating mass variance within a black hole, questioning the ability of particles to jump energy levels near the singularity.
  • Another participant suggests that merging quantum mechanics with general relativity is necessary for such calculations, indicating the complexity of the task for a school project.
  • A participant notes that changes in energy levels are typically associated with electrons in atoms, but this process cannot occur near a black hole's singularity due to extreme gravitational effects that deconstruct atoms.
  • One participant mentions a statistical quantum-thermal approach to the problem and references Bekenstein's work on mass, indicating a desire to explore similar concepts for charge, while questioning the assumptions made in existing literature.

Areas of Agreement / Disagreement

Participants express varying levels of skepticism regarding the original question, with no consensus on the feasibility of the proposed calculations or the underlying assumptions about mass and energy levels in black holes.

Contextual Notes

Participants highlight limitations in understanding the behavior of mass and energy levels in extreme gravitational environments, particularly near singularities. There is an acknowledgment of the need for a unified theory to address these questions adequately.

Who May Find This Useful

This discussion may be of interest to students and researchers exploring the intersections of quantum mechanics, general relativity, and black hole physics, particularly those looking into theoretical frameworks and statistical approaches in these areas.

HI,
I need to calculate the variance of mass released when a particle jumps down or up between energy levels
inside a black hole , i don't know where to begin
any advice will help
thanks

We have no idea what happens to mass when it gets to the singularity in a black hole, but I doubt it's still able to jump energy levels. Why do you need to calculate this?
 
its for my final project degree
helping my professor, i regret it now for choosing this subject :)
thanks anyway

Welcome to the PF.

Your professor is okay with this topic? Can you post links to other work that has been published in this area? As phinds says, on the surface of it, the question would seem not to make sense.

Wouldn't that require you to successfully merge quantum mechanics with general relativity? Seems difficult for a school project.
 
Changes in energy levels are typically associated with electrons in an atom jumping from one shell to another. This cannot happen at the 'surface' or interior of a black hole because atoms and even their constituent particles are deconstructed before they can get that close to a gravitational singularity. It probably cannot even occur in the case of a neutron star or white dwarf for similar reason. Electrons are disassociated from atoms in degenerate matter states..
 
thanks everyone for their answer
but my task is only in statistical quantum-thermal approach to the problem , i found that bekenstein already did it for mass but i need the same for charge,he assumed Q=0 , and i guess its not the same solution
i uploaded it ,its from the book to fulfill a vision - Yuval Ne'eman http://www.abebooks.com/products/isbn/9780201052893?cm_sp=bdp-_-9780201052893-_-isbn10
anything will be very helpful
thanks
