Matter and even information in a black hole (beyond the event horizon) is supposedly lost forever because nothing can get out. What if a second black hole were to pass close by? With such a trajectory that it's able to get away again, but close enough to partially undo the first hole's gravity? Wouldn't that allow stuff to get out again? (by flattening out the spacetime in between the two holes) For example, suppose you are just beyond the event horizon of a black hole, in a spaceship with enormously powerful engines, you are struggling in vain to try to get out but can't even hold your position, then a second hole passes by at high speed and its gravity is just enough to help you get to the middle in between the two holes. Then, as the holes separate again, you just stay in the middle until the holes are far enough away to allow you to escape. Free at last! You probably don't even need a second black hole, any sufficiently massive object (neutron star, maybe even a planet if you are a really short distance beyond the event horizon) could be enough to push the event horizon in a little bit and allow you to escape. Wouldn't that work? And wouldn't that, theoretically, allow all supposedly lost information to be retrieved, which means, even if this possibility is only theoretical and highly impractical, that the black hole doesn't have such an enormous entropy after all?
