Question re the Information Paradox

Islam Hassan

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...

The author is not a publicly-known academic personality.

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."

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?

Well I don't think the views of the author are exactly mainstream, if there is such a thing with this subject. If the blackhole 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.
