Quote History Quoted:
I thought a specific deal with black holes is their gravity is so great that not even light escapes. I'd say that's slightly different than the average star.
Yeah but with those same time dilation effects the human race would be stuck in this giga-slow development relative to the rest of the universe (except for other species who chose a black hole as their home star). Would the side of the planet closer to the black hole experience an even greater time dilation effect than the "shadow" side? Did that planet have a rotation so as the planet rotates the side facing the black hole slows down and over the course of each "day" different time zones speed up and slow down in time? Not to mention the whole thing about jacked up gravitational effects on everything. Does your weight vary depending on which side of the planet you are on?
Which would suggest a less than hospitable climate for agriculture.
The whole method of selecting a new planet struck me as akin to throwing darts at the wall while blindfolded and seeing what you hit. Sub-orbital satellites or atmospheric drones or some other method of exploring the planets would make way more sense than just dropping a dude off at a random spot and hoping for the best.

a planet next to a black hole is no different than a planet next to a star. if our sun collapsed into a black hole tomorrow, it would do absolutely nothing to the earth's orbit--same mass, same gravitational effects.

the relativistic effects of orbiting the first planet would dilate time so badly that everyone on earth would be dead anyway.

the second one, the surface of the planet was obscured by solid, frozen clouds.

there are others here who can explain the mechanism better, but the key point to remember is that gravity is proportional to
mass--it is mass that causes gravity. so two objects of the same mass are going to have exert the same gravitational pull. so the sun holds the earth in its orbit (they orbit each other, but that's irrelevant here). but the sun is really big, right? now crush all of that mass down into a baseball-sized object--same mass, but much, much
denser. the earth's orbit wouldn't change at all, right? since it's the same amount of mass, it's the same gravitational pull.
what's different is when you get so close to the singularity (point of infinitely compressed mass), that you would be
inside the sun's former surface. the radius of the sun--from surface to center--was 700,000km before it collapsed. once you got closer to the singularity than that, gravity would start behaving differently. think of being in a hole with really, really steep sides. the closer you get to the singularity, the steeper the sides get. the event horizon is where the sides become so steep that nothing can escape. with our sun, the radius of the event horizon would be ~3km. see the difference?
as for orbiting, time slows down with gravity. remember when they said that every hour on the first planet was 7 years on earth? in order to orbit the planet, they would have to get even closer to the black hole, meaning that the time difference gets even more extreme. when anne hathaway suggests orbiting, cooper points out that it would take hundreds of earth-years, and everyone back home would already be dead.
i agree that it was a dartboard strategy, but again, they talked about this. they only had limited fuel, and were under tremendous time pressure. i wanted to see more comms attempts, but it was a movie, and i was willing to suspend disbelief.
