Black Hole singularities in Quantum Gravity

Click For Summary
SUMMARY

The discussion centers on the complexities of black hole singularities within the framework of Quantum Gravity (QG). Participants question the existence of singularities and explore the potential for repulsive forces in QG that could prevent particles from collapsing indefinitely. The conversation highlights the speculative nature of current theories, emphasizing that a definitive theory of Quantum Gravity has yet to be established. A resource from arXiv is also shared as a valuable reference for further understanding.

PREREQUISITES
  • Understanding of Quantum Gravity concepts

TL;DR
How are black hole singularities resolved in QG ?
If singularities don't exist in QG then what prevents particles from just collapsing falling further until they collapse into a singularity? Is there a repulsive force in QG ? Is time infinitely stretched near a singularities? What else could be happening?

What is quantum gravity? I mean, which theory specifically do you have in mind? As far as I know there isn't, as of now, such a theory, so your question probably can be answered only very speculatively.
 
I'm happy with the answer for any of them.

Why is such a question difficult to answer ? Why is it not just listing possibilities and trying models for them ?

Hey, why was this changed to B level ?? I'll have you know that I am the graduatest of the graduates. I deserve the A level just as much as the next guy, even if my question betrays it!
