Black Hole Paper Outlining Process of Singularity Formation

Click For Summary

Discussion Overview

The discussion centers around the formation of singularities in black holes, specifically the physical processes involved during the collapse of a star into a black hole and the implications of singularity formation. Participants explore the theoretical underpinnings and the limitations of current models in understanding these phenomena.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant requests seminal papers that explicitly show and prove the formation of singularities in black holes, expressing a desire to understand the exact physical processes involved.
  • Another participant suggests that "singularity" refers to a breakdown in mathematical models, indicating that current understanding is limited and dependent on future developments in quantum gravity.
  • A participant questions the point in mathematical models where the breakdown occurs and speculates on the portrayal of black hole centers in popular science media as point particles.
  • There is a suggestion that the center of a black hole may not be a singular point but could encompass a larger area, contingent on advancements in quantum gravity theory.
  • Another participant expresses the view that a complete theory of quantum gravity may eliminate singularities in mathematical models, implying that they could be regularized away.

Areas of Agreement / Disagreement

Participants express differing views on the nature of singularities and the implications of future theories, indicating that multiple competing perspectives remain without consensus on the specifics of singularity formation.

Contextual Notes

The discussion highlights limitations in current theoretical frameworks and the dependence on future advancements in quantum gravity to resolve ambiguities surrounding singularities.

Can someone point me to the seminal (or any other) paper explicitly showing and proving the formation of singularities in black holes?

I'd like to learn about the exact physical processes which occur during the collapse of a star into a black hole and how the progress of those physical processes result in an actual singularity being formed rather than anything else.

Cheers!

"Singularity" is just the name we give meaning "the place where the math model breaks down and we don't know WHAT is really there".

It is generally believed that if/when we have a solid theory of quantum gravity we will better understand what is at the heart of a black hole.

SO ... better you should just ask about the formation of a black hole, not the formation of the singularity.

That seems like a very good answer. What is generally accepted as the "place" in the math where this begins?

Care to speculate why "popular" science media seem to depict (or at least imply) that the center of a black hole is populated by a point particle of sorts?

The "place" is at the exact center, but again, if/when we get a theory of quantum gravity, it will almost certainly be a larger area than just a point.

pop-science pretty much always dumbs things down to the point of being incorrect. The absolute worst case of this is the ridiculously incorrect statement that the universe began as a point and "exploded" from there. The "big bang singularity" being so described is related to the black hole singularity only in that they are both being described as "the place where the math model gives clearly non-physical results and we don't know what is really happening", but the word "singularity" is pretty much always incorrectly stated by pop science as meaning "point".

I take this to mean the interesting "stuff" of the black hole will be determined to "occupy" more than a point when there is a complete and correct theory of quantum gravity... and concurrently that there will no longer be any "singularity" in the math (at least none that can't be regularized away...) .Thank you very much for your answers.

Yes, that is my understanding.
