The Information Paradox arises in the subject of black holes because it appears that once information (matter/energy) crosses the event horizon there is no way to retrieve it. The information has essentially been removed from existence (or at least theoretical access), and this violates a conservation of information. I'd like to start a discussion whether information is ever actually lost in a black hole; specifically, I'd like to analyze the statement: Is there information, which existed in the past, that is theoretically unavailable to external observers today due to falling through the event horizon of a black hole? I'd like to restrict this thread to GR, and limit the discussion to the above specific statement and subject matter. I'm open to suggestions on how to analyze this question, but my thoughts are to follow. To the external observer an infalling object is never lost. He could continue to study such an object for all time, taking readings and measurements of the object, albeit from an asymptotically redshifted and time dilated view of it. The external observer could adjust his measurements to account for such redshifting and time dilation and record perfectly accurate data (with perfect instrumentation). Does this answer the question? There does seem to be a view in the community that reality contains some sort of a physical disconnect between what the observer sees and what has "really happened". How can we probe this? One thought I had was to launch a mirror towards the event horizon, and let the external observer watch his own clock in that mirror. It seems to me that if there is a point of last communication (from the perspective of the mirror) then there would be a terminating time T after which the external observer could no longer see his own clock. I do not believe this is the case. From Reflections on Relativity: Please Register or Log in to view the hidden image! If it's true that there exists no time T on an external clock which cannot be observed from that clock's location, after having been reflected on an infalling mirror, then I believe the answer to the question in this thread is NO and information has never yet been lost to a theoretical event horizon. We could replace any infalling candidate from the past whose existence is in question with a mirror; we could then send a pulse of light in the direction of that object today with the anticipation of reading back that pulse of light at some point in our finite future. Thoughts?
