Physicists at Caltech have devised a way to coax information back from the so-far unknowable depths of a black hole. While it's an impossible scheme to implement experimentally and involves the recapture of information from just a single particle, it's an interesting illustration of both the difficulties in truly understanding black holes and of quantum entanglement, the quantum mechanical property that seems to unify separate, individual particles across unlimited spans of time and space.
