information can leave a black hole

It is possible for information to the leave a black hole. Entanglement is a
feature of quantum mechanics that allows particles to share a much closer
relationship than classical physics permits. A measurement on one part of an
entangled system reveals the properties of the other part, even if they are
physically separated. So even if one of the entangled particles is in a
black hole we can gain information about that particle from the particle
that is not in the black hole. Moreover if a person in a black hole can
control an entangled particle that enters a black hole he can commutate with
the outside of the black hole.
