Would make new thread about this, but i can't.
I would like to report another try of old challenge from Space Engineer i made, which was braking down a ship using black hole. I mean, it was about accelerating using black hole to significant percentage of light speed and then break the ship down from this speed using another black hole. Accelerating is not a problem, but braking... Well, at my first attempt my physical velocity was 0,70c and the black hole didn't even have effect on my direction as i passed just close to the event horizon and through the accretion disk and the black hole just slowed me down just a little bit. Well, now i i had 66% of light speed, found black hole 0.24 AU large, but this time i went right into the event horizon. Just not exactly in the middle. In the time i entered the event horizon, my ship was moving 99% of light speed and inside i orbited singularity and then was catapulted out of the black hole again (was pretty cool, but not sure if Einstein would agree with this). When i was moving away from black hole, the black hole's gravity managed to only slow me down to 60% of light speed. Then i got too far away and the gravity had no effect on me anymore.
So i think my speed at the start needs to be lower or you need a bigger black hole. But i recorded this try and it looked cool, so i'll probably edit nice video out of it.
