Could i take this into the theoretical realm for a moment? If you could somehow generate your own gravitational forces, could you offset the effect of the black holes gravity? I'm not sure i'm making sense, but in the same way a planet orbits the Sun, if your craft could create sufficient gravity to offset that of the black hole and then sufficient velocity to shift the craft at very high speed, could you not get in very close orbit to a black hole, perhaps passing over the event horizon, close to the centre and slingshot out again? Silly thought probably, but it just kind of popped in there. [rofl]

When a massless photon can't escape the Black Hole, a spacecraft surely couldn't either. To be even with the photon the craft would need all the energy of the Universe and it still wouldn't be enough. Remember that we were discussing a free fall to the Black Hole, fighting against its gravitation field with any remarkable counterforce would just end in splatting the craft and the astronaut. [yes]
