I don't know why you are getting down voted, I mean the science in that movie is ludicrous.

!!!SPOILERS SPOILERS SPOILERS!!!

Gravity moves back in time? No, it doesn't, it has a speed of light delay. If it moved back in time, we would feel the gravity from, say, every point that the earth had been ever. And every other planet. And the gravity would implode the universe. And mcconaghy falls into the black hole, and sure they catch him with the tesseract, but only after he gets the data that they otherwise can't get, so he must have gone past the event horizon, by diving straight in... Something that would for sure kill you from the gravity dilation. And the time dilation on the wave planet makes no sense, they experience like a million times slower time on the planet, which is due to the black hole, but by hovering in near orbit it is a 1-1 ratio? It should still have huge dilation, unless it is very far away, but we can see the planet from its orbit.

Also, so many plot holes are gaping... Blight is killing all the crops, what do they do? Make all the scientists and engineers become farmers, instead of trying to find a cure. Mann knows that the planet is uninhabitable, but still wastes time and fuel for a day before he tries to go rouge. Why wouldn't he just tell them they need to leave right away? What are they going to do, not let him come? How is he even going to operate the fetus thing, he's not a biologist he's an astronaut.

Granted, mcconaughy's acting was amazing, the sound track was great, cinematography and special effects were good, and it was all in all a very good and entertaining movie. But the science was inarguably flawed. I'm not trying to rain on any parades, Nolan is one of my favorite directors and I don't let scientific flaws stand in the way of how I appreciate a movie, but that also doesn't mean I don't pretend they aren't there.
