The two researchers, Remo Garattini and Kirill Zatrimaylov, recently published a paper on warp drives going into a black hole. They found out that a warp drive can cross the black hole’s horizon and send a light signal to the outside, and also that the black hole’s gravitational field can reduce the amount of negative energy density required to sustain the warp bubble.

Warp drive is science fiction. Entering a black hole is death. Crushed to infinite density.

I might be be wrong, but I think if you fell into a black hole feet first you body would stretch out like spaghetti. Time will dilate in a way where your feet will be in the past or future (cannot remember which) and your head would be in the present. If you were to look left or right you would see the back of your head.

Cool but still super theoretical. The math relies on magic. Negative energy that probably doesn’t exist. Its hard to know and we shouldn’t stop looking.

Correctly they suggest escape is possible & imply that it actually takes less energy to do so than the same warp in flat spacetime which is interesting.
In fiction there is at least one Startrek novel where two starships (both called Enterprise) more than a century apart cross the even horizon of an intermediate mass black hole. But because of the unusual spacetime conditions they are able to assist each other in a rescue operation of a third craft.
That was fiction, but some formulations of relativity do suggest that closed timeline loops could be possible for superluminal flight within the last stable orbit of a singularity. Which implies that such navigation is about picking a moment in time to exit & not a position in space.

Look, I’m on board, but I’m not going to be the first to try it.

Not a physicist, only a sci-fi enthusiast so I’m just talking outta my *ss here, but….
Below the event horizon of a Black hole, the space time curvature is extreme to the point that all possible paths that you can take leads inwards towards the singularity.
The warp drive is capable of bending space to create a localized space time bubble for the ship to “surf” along in.
I wonder if a sufficiently powerful warp drive would be capable of bending the downwards cascading space time below the event horizon enough to create an escape. I bet it would violate a buttload of physical principles if it could. I am not smart enough to say which ones though…
