Wiki article on black hole paradox....
Seems the problem has been resolved;

The black hole information paradox results from the combination of quantum mechanics and general relativity. It was a contentious subject for science since it violated a commonly assumed tenet of science—that information cannot be destroyed. See Liouville's theorem (Hamiltonian) and unitary transformation.
In 1975, Stephen Hawking and Jacob Bekenstein showed that black holes should slowly radiate away energy, which poses a problem. From the no hair theorem one would expect the Hawking radiation to be completely independent of the material entering the black hole. However, if the material entering the black hole were a pure quantum state, the transformation of that state into the mixed state of Hawking radiation would destroy information about the original quantum state. This violates Liouville's theorem and presents a physical paradox.

Astronomers using NASA's Chandra X-ray Observatory for research are hosting a media teleconference at 1 p.m. EDT Wednesday, June 21, to explain how black holes light up the universe.
