This is a trick. The effect depends on a far away observer.

Imagine you're moving towards a blk hole. As you approach it, your speed goes to c. Folks on Earth see you decelerate and hang at the event horizon. The guy on the ship sees the blk hole accelerating towards him.

To an observer on Earth, the clocks on the ship slow down and the mass of the ship goes huge. All the guy on the spaceship sees is the black hole accelerating towards him and eventually he becomes one with the hole. Like a guy crashing into the wall.

On Earth, it seems the guy driving the ship has slowed down for some reason and parked his ship at the event horizon. This is the nature of the apparent repulsive force. The guy on the ship doesn't believe in that force.

I don't think that's what Felber is talking about.

Does that mean the force of gravity the ship exerts on the Earth increases?
