Two things suck...

I think Interstellar was a very interesting movie, and I enjoyed it a lot. But there a two things I find damn stupid and really poorly executed in the story telling and so I must blame Nolan for that foolishness.

1: when he returns to a better future and now an old Murph, they pretty much show no true interest and her new family seem to just brush him off. I know, I know the movie sort of just explain this that she wanted to see him before she would die.. but I found that whole thing utterly poorly executed in the storytelling. Not least because the whole damn movie was about him coming back home to her... talk about an anticlimax

2: he went into the black hole and communicated back in time to her via some alien gizmo .... holishit wait what???? And no one care one bit what the hell happened. Yes again I know Murph said no one believed her when she talked about a ticking clock telling her the secrets of the universe... (did she really try to say that to her NASA peps)... but even Murph cared not at all how the hell he did it... truly this was the most mind blowingly fantastic thing about his whole tale... unbelievable miss in the storytelling .... and sooo easy to fix.

3: also, what about his son and his family line?

4: and then for some reason he goes to rekindle with Brand, because ... sure they love each other now... what, when was this ever shown during their travels? In fact, it was made clear Brand was in love with one of the stranded explorers whom she was believed to end up with... but ind the end, now Cooper was her love interest..... yes I know again that the movie showed us her love was dead and buried on that planet... but Cooper did not know this. Confusing.

5: why not send supplies to Brand first btw, I mean this better future seem to be pretty resourceful... but he just take off.

Okay, I said two things .. but still the movie could be brilliant and then just falls apart in this final act. In ways that could so easily have been fixed.

Am I wrong ?

If a planet has enoough gravity to dialate time one hour into 7 years I'm pretty sure youd be crushed by your own wait. Also why would they want to set up on a planet that close to a black holes event horizon.

It was orbiting a black hole that caused the extreme time dilation, and also the extreme tidal wave. It wasn't the planet.

If the orbit is stable, then the planet could work, in lack of some Goldilocks zoned heaven.

.... but of course why not send down a probe first...

I didn't mean to say the planet was causing the gravity but was saying being exposed to that kind of gravity would crush you regardless. You'd be way to heavy you'd be a distorted puddle of mush. The ship even made of metal would have been crushed.

Also if the tidal wave can be lifted that high from the surface.... wouldn't we? I mean the mass in a few astronauts and a lander spaceship is nothing compared to the mass of such waves.

Granted water is a fluid, but still...

You all make good points, and not to get too technical, but what if them martians zapped everyone with their fancy ray-guns and turnt em into goo?

It's because the planet is moving. You do not feel the effects of gravity as you are falling, which is why you feel weightless when skydiving. That's essentially what an orbiting planet is doing. It is falling, but missing the object it is gravitationally connected to. You, the planet and its oceans are all being pulled at the same rate, so there is nothing for you to be "crushed" against. Just like if you were standing on the moon, you would not feel earth's gravity.

When your that close enough to ant even horizon your crushed. And if a ship could literally be in an orbit further out from the black hole that is not as dialated. If that were the case approaching the planet means your being exposed to accelerating growth in gravitational force that would stretch your body and terminate all your life functions. The fact that the ship can be on such extreme ends of a time dialation shows this.

Spaghettification and time dilation are two separate phenomenons though. I think a planet would reach the '1 hour = 7 years' time dilation point much further away from the black hole than the point at which spaghettification begins. In fact, we all experience time dilation just by moving. It's just not something we can measure with our senses because they all scale with the dilation. But once spaghettification begins, you are so close to a black hole that you are on a one-way course to infinity.

I think the argument that was used in the film was that the black hole was suppermassive so you'd have to be extremly close to the event horizon to see spegetification yet the black hole in the film was small enough that the difference between 1 hour being 7 years was only a few hundred thousand kilometers indicating the black hole wasn't that massive. The film wanted to have the time dilation as it was a cool demonstration in the plot but not massive gravity difference it would have required.

I see your point, but I'd kinda need to see the equations. Going from 1 hour to 7 years in the span of a few hundred thousand kilometers may sound like small distance for such a large time dilation, but we're talking about something that is scaling to infinity. A few hundred thousand kilometers closer and you could scale into thousands of years per hour. A few hundred thousand kilometers even closer and you could scale into millions of years per earth hour. Yes, you're not getting much closer to the supermassive black hole that's extremely far away, but you're not getting much closer to infinity either. See what I mean? It's not really something I can criticize the film for unless I can see the equations.

What I mean to say is if the force of gravity is shifting that fast your obviously not near a super massive black hole and closer to a normal one that would subject your body to stretching which would have killed you if you crossed through it that fast. It seems I'm not the only one making this observation it looks like its been discussed on reddit and sort of glossed over on science blogs that would rather focus on the depiction of the black hole itself in terms of rendering rather then the scale of gravity. IE the movie was depicting the visuals of the black hole so well they glossed over the artistic lisence used by the plot in its eagerness to show time dialation.

The equation for time dialation is

dt'=dt*sqrt(1-(2*G*M)/(r*c^2))

How do you know the force of gravity is shifting too fast for a supermassive black hole though? We've already accepted that a supermassive black hole does not subject one to that level of extreme tidal force as a stellar mass (normal) black hole. So now we have to look at how a supermassive black hole subjects one to time dilation and at what distance. And the only way I know of to get there is to look at equations that factor in size of SMBH and distance from it/Gargantua. I don't think we can simply go by tidal force, because it is a separate phenomenon than time dilation.

No a super massive black hole wouldn't have had such a rapid differential of gravity with respect to the volume of space. IE in order to not be spaghettified would have the script requiring a super massive black hole. Yet the fact that the amount of gravity shifted so fast indicates this isn't a super massive black hole. The film is just inconsistent in its depiction of the black hole. That is all. I'm also just more skeptical then you.

Here is the most extensive research I've seen on the subject. He talks about the Schwarzschild solution vs the Kerr method which takes into consideration the rotational speed and angular moment of the black hole.

Also, Gargantua is neither a supermassive black hole nor a regular black hole. It is somewhere in between around 100 million solar masses. Using the Kerr method, there are potential stable orbits around the black hole that duplicate the "1 hour = 7 year" time dilation.

I will concede that the time difference between the planet and the guy in the ship was most likely greatly exaggerated. I'm not 100% certain, but I think the guy in the ship would've experienced the majority of the same time dilation they were experiencing on the planet.

The guy on the ship aged a decade or more. The film depicted him as living in near earth time so that the earth would have aged roughly the same as him.

It's been awhile since I've seen the movie, so he could've been a lot further away from the planet than I remember. The thing is, even though Nolan hired theoretical physicists to help with the movie, he's known to stretch things. Kinda like how in Inception he was using the untapped portion of our brain energy mumbo jumbo to explain how time moves differently in deeper dream states. So he's no stranger to stretching the rules of time dilation even in his own previous film. Like I said below, I really do think that having that guy age in earth years is where Nolan fudged it the hardest. There was just something about it that didn't mesh logically when I first saw it, as if Nolan was up to his old shenanigans.

I know the visuals about the worm hole and the black hole were pretty spot on and required some super computer resources. But the depiction of how quickly the time dialation zeroes out the further away you went from the black hole was very stretched since it was a super massive black hole being depicted.

Apparently he actually dies either going into the black hole or when he comes out of it. The sequence when he is rescued and sees his daughter 1 last time before moving on was a vision/hallucination or his bodies way of calming himself before the inevitable.

This is why he doesn't interact with his extended family etc as it was a positive dream sequence where he imagines that he made it back to see Murph and that his plan had worked and she saved humanity like he had hoped. And that his old house was still preserved just as he remembered it.

Basically it is proof of what Dunn was saying about 'seeing your children' before you die.

I doubt this was the intention from the movie maker. Remember several of the interview scenes in the very beginning of the movie, are taken from that ”musem” setup of his house in the end. Perhaps this proves little, but I wanted to make a note of it. Anyway, he did not see his son in this ”dream”, and shouldn't he?
