@SpaceEngineer : For example, the Miller planet is completly impossible, a planet with such a time change (thus very close from the Black Hole) would be completely destroyed by the Roche limit, and, anyway, there couldn't have liquid water if so near from the Black Hole (not speaking about people on it considering the size and the color of the disk Black Hole , I think that it's probably not very safe to take a walk so near from it with all the Gamma and X Ray you would receive, even if it's not a big disk, there are supposed to be very. VERY VERY close from it.). All people and ships in the movie should be instantly carbonized by the heat and the rays, and the crushing gravity.
Also, the fact that they take off quite easily with their small starship from Miller planet, when they needed an enormous space rocket to take off the same way, from Earth (where gravity is lower than on Miller's planet, which is "only" 30% higher, when time is so changed...another contradiction). Unfortunately, it's only a part of the issues of the movie...Oh, and, at the end, seeing people playing baseball, in the Torus, I think, it's also a big problem on a physical point of view. Don't they know the Coriolis strength, and the fact that "gravity" will change quickly, while the ball take "altitude" ?
Last thing, how can planets form around Gargantua ? It doesn't seem there is stars, but there are planets ? Very strange.
Well, actually, there are so many scientifical issues...
There are also some very funny moment when people in the spaceship discusses very elementary physical things (for the audience, of course). I know that, if they didn't, there wouldn't make a movie, but it doesn't make a good story anyway...
The last moment, when he leaves the black hole and is alone in the void of the space and a spaceship comes to "rescue" him is...well...fun ? Only the Heart of Gold and its Infinite Improbability Drive of H2G2 can do this (really, think of it, in the infinity of space, there was a ship to rescue him ! Just there. Very lucky, indeed)
Anyway, even if it was completely exact on a scientifical point of view, i still find the scenario very bad...that's why I don't understand so many praise for this movie.
Well regardless of your opinion which I think everyone is entitled to one and I am also entitled to tell you your opinion is shit. Regardless of what I just said you changed my view and made me realize that interstellar is unrealistic but it is just a movie so it doesn't matter and I think that interstellar is one of the best movies out there
