For years, some scientists contended that black holes swallow everything, including the information associated with the particles they suck up, and that this information can never be recovered. The problem with this idea - the chief proponent of which was the legendary Stephen Hawking - is that it violated a law of quantum mechanics.
A few years ago, Hawking changed his mind, but his contemporaries weren't necessarily convinced of his solution. Now Penn State University's Abhay Ashketar and his colleagues say they've come up with a more complete description of how information that falls into a black hole can still be retained. Physicists seem mixed on Ashketar's solution, though most appear to believe it is a promising approach.
The work will be published in the journal Physical Review Letters.

one of the old theories explaining the information paradox is that it explains a black hole as being a p brane, which, when hit with a partical (represented as a closed string) hits the p brane, waves form as the energy is transfered. When the waves collapse, the information of that partical is realeased.

If an Image can be stretched to an invisible frequency I am sure it can be Condensed. If Information goes into a black hole, it should be rebuild into a different radiation of energy, at a precievable future. Really, just transforming all information one step up, or down... err. Is there a black hole that pushes out image and frequency or is there only stars? Dam...
White Light could really just be all the light of the universe in a small strong force, but then It would make sense that it LOOPS like that.
The reason why Hawking's "contemporaries" didn't buy his reason is supposedly because they felt that it did not solve his original belief (that after a black hole evaporates it would still leave behind its singularity, where it was said that information would be lost forever).
Ashketar's group only used two demensions (1 time, 1 space) in their model. It is not known if the information being restored would work in more dimensions.
John Preskill, who bet with Hawking and Kip Thorne, does not seem to be buying into this new theory, as there remains doubt due to work in 1994 which indicated that models like this new one would still give information loss.
Well I should read entire story before commenting but I simply do not have the time. Do you have the time to read comments of others? I do since they can either be more informative or simply entertaining. I do not necessarily buy into the once in then no info escapes line of thinking. Many propose that black holes are empty space. As true as that may be there is still mass/frequency being ejected in AGN form. This involves pulses of a sort of the magnetic-kind. This is not an oter or inner horizon evebt. Of course I refer to rotating black holes. In non-rotating the illustrious claim the black hole literally 'pinches' shut. Then again there are those that say there is a 'dark crystal' located in the black hole. I'd guess there are nearly many opinions, conjectures & hypotheses as there are known black holes.
Hawking's theory to explain how information can be lost into a black hole is possible, and allowed by the multiverse theory of another universe without a black hole, is not a valid argument.
Part #1: Logical Error with Approach
If you believe that for each universe within a multiverse, there is a specific degree of variation to each and every universe, than Hawking's approach to information loss is not valid. If you collected all of the particles in each universe, it would create a unique pattern, universal signature, or better yet, a 'unique pattern of information', which describes the uniqueness of the universe. If a concept of a black hole exists in a universe, collects, and negates information, i.e. information loss, that information is forever lost for that universe, because each universe is unique and contains a unique 'information signature', which describes the universe.
Part #2: Alternate Proposal for Information 'Loss' to 'Translation'
Having an alternative universe within a multiverse, that contains no black holes, and cannot negate information, allows for an imbalanced approach to information management. If we look at a multiverse as a balanced equasion, a continuim, cyclical flow of information, you would have some universes, which 'flow out', or appear to negate information through a black hole, and to balance, I propose you have that information 'translated' into an alternate universe of another unique perspective, or variation of the previous universe. Each translation 'layer' (currently called a 'black hole') from one universe to the next would alter information with a unique signature, or perspective. Like the game of 'telephone', passing a message from one person to another, or perception interpretation, we have a translation algorithm, a so called 'Black Hole', which takes information from one perspective, one universe, and translates that information \ energy into another universe, which is slightly altered based on that translation algorithm.
Capture, Alternate, Explode with a unique pattern of information, just as someone racking up a pool table again, and breaking up the balls. Each time you are left with the same amount of balls on the table, starting out as a central point of collected information, then scattered by an outside ball, which breaks up the collected information into another unique patten of new information.
Part #3: Shape proof for Multiverse with Information Translation Model
As a single point of passage, a 'black hole', conical shape with a wider and a narrower opening at the two ends, if the so called 'gravity well' ingests all energy, including information, that energy and information is not lost, it is translated into an alternate, yet 'tangible' universe within the multiverse, and the reason the alternate universe is a variable degree of difference from our own is due to the method by which the information and energy is thrust through the 'translation matrix' (so called Black Hole). To extend the use of our pool table analogy, if you had a pattern of pool balls scattered on a table, and you then lifted the table to force all of the balls into one pocket, they would not maintain the pattern of balls (Information Pattern) on the table, and after going through this 'single lane' or channel, on the other side all of the balls, the composition elements, but would form a new pattern, or organization of balls.
Extrapolation of the shape of a 'multiverse' is now possible based upon the above theory.
The idea of any paradox is intriguing but I believe that I can see through the Black Hole Paradox: it could leave a number of red faces!
The paradox seems to depend on matter/energy/information being lost into the singularity that is deemed to exist at the centre of a black hole. But:
A singularity is the ultimate state of an infinite process of compression/compaction. This infinite process will take infinite time that has not yet passed. Thus, no matter how close some may come, singularities do not and will not exist in finite time.
No matter how difficult it may be to un-squeese a near infinite squash, nothing has been lost nor will be in finite time.

What exactly do you mean by "information"?
Consider all the books that you've read, then consider all of the books you haven't read. The difference between them is the ones you've read are information and the ones unread merely data that you've yet to process.
Black holes are in a sense Natures de-bugging program.
