Black Hole singularities in Quantum Gravity

[Intrastellar]

TL;DR Summary

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!

Looks like a very helpful resource, thanks!
