A collection of papers examining an "observerspace" treatment of how general relativity and quantum theory describe black holes. For instance: When objects fall into a black hole, an outsider sees those objects to be slowing as they approach the event horizon, and merging into an arbitrarily-thin film at (or at a Planck distance above) the mathematical horizon surface. The Membrane Paradigm essentially asks what the consequences would be if we treated this apparent film of material, which is all that we can see of the hole, as if it was the hole's physical reality (after all, all our interactions with the hole would appear to us to be interactions with this film). The Membrane Paradigm offers a fast "engineering" approach to modeling and visualising the behaviour of black holes and their associated Hawking radiation (which can be treated as conventional radiation emitted by the hot membrane surface).
A pedagogical introduction to the physics of black holes. The membrane paradigm represents the four-dimemnsional spacetime of the black hole's "event horizon" as a two-dimensional membrane in three-dimensional space, allowing the reader to understand and compute the behavior of black holes in complex astrophysical environments.

This pedagogical introduction to the physics of black holes emphasizes the "membrane paradigm", which translates the mathematics and physics of black holes into a form accessible to readers with little knowledge of general relativity but a solid grounding in nonrelativistic physics. This is accomplished without resort to approximations or loss of content. Instead of treating a black hole's "event horizon" as a globally defined null surface in four-dimensional space time, the paradigm views it as a two-dimensional membrane in three-dimensional space. Made of viscous fluid, electrically charged and conducting, with finite entropy and temperature but no power to conduct heat, this membrane is seen as having familiar properties that enable the reader to understand intuitively and compute quantitatively the behavior of black holes in complex astrophysical environments. … (more)
