[Interstellar] How did Cooper escape the black hole? And did the ranger-ship that he stole from Cooper Station have enough fuel to make the journey back to Dr. Brand's planet?

Two questions I had from the movie!
gpt
- The 5th-dimension future humans that provided the wormhole in the first place were capable of significant space-time manipulation. They likely retrieved Cooper from the black hole once he had successfully delivered his message.

- The thing about 'fuel' is that you don't actually need it to keep going - just to get started moving. The original Rangers were already enormously fuel efficient to achieve both landing and SSTO without refuel. Another thing to keep in mind is that the less your mass is, the less fuel you need to consume to produce the same acceleration; the future Rangers were quite a bit smaller than those used in the desperation mission.

- It is worth nothing that apparently the official novelization has Cooper wondering if the new Rangers use the gravity manipulation his daughter invented to propel themselves.
