Well if a black hole attracts objects using its gravity it would repel the "anti-grav" vehicle? So you can't drive it in.What will happen if a ANTI GRAVITY vehicle is driven into a BLACK HOLE?
That's not too different than the simplified explanation of Hawking Radiation. Virtual particles of positive mass get sucked into the black hole, and those of negative mass are radiated away. So, your friends in the regular vehicle are sucked in, and you ride your antigravity vehicle like a surfboard and get ejected right out of the galaxy.What will happen if a ANTI GRAVITY vehicle is driven into a BLACK HOLE?
As long as you are not sucked in near the black hole (which would need to be beyond the event horizon), this need not happen. The person will feel normal gravity from the black hole, plus the accelleration of the antigravity ship as it is repelled away from the black hole. I guess this would effectively double the gravitational/acceleration force compared to a ship using thrust to remain stationary, because presumably antigravity would create a negative accelleration compared to normal gravity. (assuming the person is much less massive than the ship)I'm surprised no one has mentioned--The vehicle itself may be anti-gravity, but you're not. You'll be sucked right through the miniscule cracks and holes that are in every material.
Needless to say, you would not survive.
That is a very good point. I was picturing driving INTO the black hole, which would mean you're within the even horizon, but I guess that was never specified.... I suppose this decision is up to the OPAs long as you are not sucked in near the black hole (which would need to be beyond the event horizon), this need not happen.

Of couse, at distances moderately close to the black hole, this force may be very strong (multiple g-force) such that it drives you to the floor and might even kill you. The black hole gravity might be comperable to a massive star, and typically that is not strong enough to squash and squeeze people through cracks when outside the event horizon.
But inside the event horizon getting closer to the center of the black hole, tidal forces are going to stretch and squeeze you into spaggetti, even without the the antigravity ship.
I think the force gradient well outside the event horizon is sufficient to pull a human apart. Due to the inverse square law, the smaller the black hole, the stronger the difference will be over the length of a human body.But inside the event horizon getting closer to the center of the black hole, tidal forces are going to stretch and squeeze you into spaggetti, even without the the antigravity ship.
That's doubtful. Do you have a calculation to show that?I think the force gradient well outside the event horizon is sufficient to pull a human apart. Due to the inverse square law, the smaller the black hole, the stronger the difference will be over the length of a human body.
Probably. Certainly those super-massive black holes would have negligible tidal forces at the horizon. I'll be paying more attention to their wording in the future. They keep rerunning those shows and I can't resist watching them.I suspect they were referring to the monsters in the center of our galaxy. There you could wander in and not notice until it was too late.
