Hawking radiation & Information loss

Click For Summary

Discussion Overview

The discussion revolves around the implications of Hawking radiation on the information loss paradox associated with black holes. Participants explore whether the absence of Hawking radiation would affect the accessibility of information contained within black holes and the nature of information loss.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that if Hawking radiation is not proven to exist, then information would remain inside black holes and the information loss paradox would not apply.
  • Others argue that the absence of Hawking radiation would lead to information loss, suggesting that if Hawking radiation is real, the situation regarding information loss becomes more complex.
  • A participant questions the implications of no Hawking radiation on the existence of singularities and the nature of information, indicating a lack of clarity on these concepts.
  • There is a suggestion that if Hawking radiation does not exist, black holes would not evaporate, leading to an increase in event horizons over time.
  • Another participant references Stephen Hawking's views, noting that classically, black holes could be thought to contain information indefinitely, as they would live forever.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between Hawking radiation and the information loss paradox, with no consensus reached on the implications of the absence of Hawking radiation.

Contextual Notes

There are unresolved assumptions regarding the nature of information within black holes and the conditions under which information loss occurs. The discussion reflects varying interpretations of theoretical concepts without definitive conclusions.

What if there is no hawking radiation i.e if it is not proved..i think it is not yet proved...so will it have any influence on information loss paradox..if there is no hawking radiation then the information would be inside black hole and not accessible..so there is no information loss paradox if there is no hawking radiation...any comments..

I'm no expert but wouldn't that mean you don't have a singularity? By "information" do you mean subatomic identities? I understand I am working at a very basic level here, just a curious layman.

even if anyone prooves that there is no hawking radiation then how will black hole evaporation take place. hawking radition is the one which causes the decrease in the event horizon. so the black holes will be hawing increasing event horizons.

It's the opposite. if there is no Hawking radiation then for sure there is information loss. If Hawking radiation is real, then the issue is less clear. If th eradiation is truly thermal, information is still lost. That's the whole question: whether or not the information is radiated away in the form of subtle correlations in the radiation.

if there is no hawking radiation,then information would be inside the black hole but not accessible to our world...u said that information is lost if there is no hawking radiation..how is that?
 
Even hawking himself said in his information loss paradox paper,classically, there is no information loss in black holes since the black holes live forever,it could be thought that information would be inside the black hole.
