Movie Interstellar - Question about Escape Velocity
The movie Interstellar shows people on a water planet where time is dilated so much that 1 hour is equal to 7 years back on Earth. Even though they lift off from Earth using a Saturn-V two stage rocket, the leave this water planet in a shuttle craft.
It has been pointed out that the consultant for the movie parked the ring in a stationary orbit 10 AU from a black hole that is 100 million solar masses while the shuttle craft travelled to a planet that was 1 AU from the mass. The shuttle then lifts off from this water planet and returns to the ring. On the planet, time is dilated by 60,000 times.
What velocity would you need to achieve to go from 1 AU in this scenario to 10 AU? Also, by my calculations, the planet is travelling at 99% the speed of light while the ring would be travelling at roughly 1/3 the speed of light. How exactly would you dissipate that much kinetic energy using just chemical engines?
