PBS Space Time episode on the black hole information paradox, covering how black holes seem to destroy information, the no-hair conjecture and the proposed role of the event horizon. It is part of a series on black holes.

HN recommends it as a clear explanation of how information may be encoded on a black hole's surface.

By my understanding of the theory, yes (according to some unproven theories). The information can be imprinted on the surface of a black hole (and, later are dissipated by imprinting on Hawking Radiation). This is also the principle that led to our theoretical understanding that the maximum amount of information that can be contained in a volume is bounded by the _surface area_ of the volume. This is the Holopgraphic Principle: [LINK] . There's a great PBS Space Time youtube video on this concept, which explains it far better and more accurately that I ever could: [VIDEO]
