No, the theory that the stuff that issues forth is completely RANDOM. Hawkings is famous for coming up with the idea of Hawking radiation: there's a standard principle in quantum physics where pairs of particles spontaneously manifest and then annihlate each other so fast that you can't detect. them. These are called pairs of "virtual particles." Hawkings predicted that sometimes, such a pair would manifest just outside the event horizon and that sometimes, one particle would fall into the black hole while the other would escape. In other words, the black hole would essentially be emiting radiation! Since there's no way this can happen without some energy exchange, he assumed that there would be a net loss of mass when this occured (never understood that part). The idea is that you can't predict what kind of radiation would be emitted--that it would be totally random. In essence, a black hole would eat information (what went into its creation) and only completely random noise (Hawking radiation) would ever come out. He's now said he was wrong: in some strange way (another one of those things that science writers gloss over), at least SOME information about what went into a black hole CAN make it back out, so the radiation isn't completely random.
