Singularity After Black Hole Evaporates: What Happens?

Click For Summary
SUMMARY

The discussion centers on the fate of a singularity when a black hole evaporates, highlighting it as a significant open question in quantum gravity. Participants emphasize that a singularity represents a breakdown in current mathematical models, making it difficult to ascertain its nature. Two primary questions arise: whether a singularity forms during black hole collapse and, if so, what occurs during black hole evaporation—whether it vanishes, leaves a remnant, or undergoes another transformation.

PREREQUISITES
  • Understanding of black hole physics
  • Familiarity with quantum gravity concepts
  • Knowledge of mathematical modeling in physics
  • Awareness of black hole evaporation processes
NEXT STEPS
  • Research the implications of quantum corrections on singularity formation

What happens to the Singularity when a Black Evaporates out of existence?

"Singularity" just means "the place where the math model breaks down and we don't know WHAT is going on", so it it not a "thing" that can be discussed in that way.

This is one of the major open questions in quantum gravity. Actually it's two questions: (1) does a singularity even form in the first place, or do quantum corrections make something else happen instead? (2) if a singularity does form, does it disappear when a black hole evaporates, or leave a "remnant", or something else?
