Question re the Information Paradox

Click For Summary

Discussion Overview

The discussion revolves around the black hole information paradox, exploring various hypotheses regarding the fate of information in black holes, particularly in relation to Hawking radiation and the event horizon. Participants examine the implications of black hole evaporation and the potential existence of remnants or modifications to quantum mechanics.

Discussion Character

  • Debate/contested
  • Exploratory
  • Conceptual clarification

Main Points Raised

  • One participant suggests that information is not lost in a black hole but can be viewed on the event horizon, raising questions about the implications as the black hole shrinks through Hawking radiation.
  • Another participant challenges the credibility of the source of the claim regarding information and the event horizon.
  • A later reply references alternative theories, including the possibility of information being contained in a Planckian remnant or modifications to quantum mechanics that allow for non-unitary time evolution.
  • One participant questions the existence of particles or matter that shrink below the Planck scale, pondering whether they can still be considered to exist.
  • Another participant expresses skepticism about the mainstream acceptance of the views presented, suggesting that if a resolution to the paradox existed, it would be more widely discussed.

Areas of Agreement / Disagreement

Participants express differing views on the resolution of the black hole information paradox, with no consensus reached on the validity of the claims or the mainstream acceptance of the proposed theories.

Contextual Notes

Participants reference various sources, including articles and Wikipedia, but note that the credibility of these sources may vary. The discussion highlights the complexity and ongoing debate surrounding the topic, with unresolved questions about the nature of information in black holes.

The black hole information paradox is resolved by considering that "...information is not lost in a black hole, but that all of the information of what is inside of a black hole can be viewed on the event horizon".

As the black hole gets smaller and smaller through the emission of Hawking radiation though, the event horizon is also shrinking. If I understand correctly, at a certain point (Planck length?), the size of the black hole approximates nil. At this point, the black hole, its event horizon and the information contained therein all disappear. So information is effectively destroyed all the same...I don't understand...

In this 2011 article, second to last sentence of the last paragraph:

http://taper100.hubpages.com/hub/The-Black-Hole-Information-Paradox-Explained

The author is not a publicly-known academic personality.

On the Wikipedia:

I did however find the following which may be a reply to my original query:

"Other possibilities include the information being contained in a Planckian remnant left over at the end of Hawking radiation or a modification of the laws of quantum mechanics to allow for non-unitary time evolution."

"Other possibilities include the information being contained in a Planckian remnant left over at the end of Hawking radiation or a modification of the laws of quantum mechanics to allow for non-unitary time evolution."I guess a subsidiary question is if particles/matter shrinks to below the Planck scale, can we say -for all practical purposes- that it still exists?IH
 
Well I don't think the views of the author are exactly mainstream, if there is such a thing with this subject. If the black hole paradox were solved I would have thought we would have heard about it and discussed it quite a bit on these fora. There is a discussion about this in progress at the moment, a bit of a search will find it.
