So as I understand it, Hawking theorized that due to the behaviour of virtual particles on the event horizon of a black hole, eventually the black hole would "evaporate" through what was coined the Hawking Radiation. But what I'm curious about is Hawking's interpretation of the event in that information would eventually be lost. Is this truly the case? How is information actually lost inside a black hole? Why is it that a positive particle can escape the velocity of a black hole yet a negative particle can't? Are positive particles for a lack of better words "magnetically repelled" by the black hole? I just don't understand how this concludes that information has been lost, and why it requires Susskind's solution of the Holographic Principle to resolve this issue. Any input is appreciated!
