In the docking scene where Coop is trying to dock the service module to the partly damaged Endurance, the Endurance is spinning around its center axis. As the ship was damaged around the perimeter it would spin around its new center of mass, that would be off axis. The docking bay itself would revolve around this new axis, making alignment much harder.

Correction: It's not explained in the movie itself, but any kind of craft that has to take distribution of weight into account (e.g. Larger ships, airplanes), has some form of (semi-) automatic mechanism to rebalance itself, for example by pumping fuel into another section. A spacecraft that is designed to revolve around itself and features detachable cargo modules etc., sure as hell will have some form of automatic weight redistribution as well, so as not to off-center the whole craft when someone goes to the toilet 90° away.

When Cooper is in the 5th dimension, he only "sees" Murph's room so he uses the books and the watch to communicate with her, but she takes the watch off the house and takes it to the lab in NASA and the watch is still "shaking" in Morse outside the room and the house, where Cooper can't manipulate gravity.

Correction: Cooper is not *only* manipulating gravity, he's effectively reprogramming the laws of physics. He permanently affected the watch so that the second hand only ever ticked out his coded message, no matter where it is taken.

Phixius

When Cooper begins transmitting the data in morse code through to Murph's watch, he starts with dot, dot, dash, dot, which in morse code is F. Later, after Murph has written out the morse code when and begins writing the equation on the chalkboard, it appears the first thing she has written is S, even if Cooper transmitted the first letter as an F.

Casual Person

Correction: What Cooper is transmitting is data that TARS recorded and might start with F. Murph on the other hand is working on an equation that only incorporates this data. She is also seen working on the morse message and presumably prior mathematic work before ever writing anything on the board. The second letter Cooper morses is 'L' (dot dash dot dot). The third an 'O', which is entirely different from what Murph actually writes on the board. FLO might be an easteregg to the film's original working title 'Flora's Letter', Flora being the name of Christopher Nolan's daughter.

The crew land on Miller, the ocean planet, in water a foot deep, and an unbroken wave - a tsunami - of at least 100 feet high reaches them. However an unbroken wave is only possible if the average water depth is - as a rule of thumb - not less than the wave height, anything much less must cause the wave to break. There could be deep water further out through which the unbroken wave can move, but it will break before it reaches the very shallow water in which the astronauts are standing. Recall the footage of the 2004 Indian Ocean Tsunami and the 2011 Japanese tsunamis - the waves were broken where they moved over very shallow water. A consideration of the actual movement of water particles as a wave passes reveals that it is physically impossible for a hundred-foot high wave to move unbroken in water only a foot or two deep.

Correction: The planet was orbiting a black hole. The waves were likely caused by the gravitational pull of the black hole. The rule-of-thumb from the original post is not likely to be relevant in that situation.

SPOILER: When Coop is on Cooper Station at the end, we're told it'll be a couple of weeks until his daughter arrives. We skip over that time period fairly quickly, and he eventually sees Murph, who tells him to go to Brand, who's all alone on Edmonson's planet, through the wormhole. Why does it take him so long to think that might be a good idea?! As soon as he's aware what's happened, why doesn't he tell everyone what's happened and where she is, so a rescue party can be sent? Instead he sits around on his recreated front porch, wondering what to do with himself, before finally seemingly going after Brand alone.

Correction: Cooper does not know that Brand made it to Edmondson's planet for sure. The plot is consistent with the assumption that Cooper has told NASA what happened from his perspective. Why would NASA take the huge risk of mounting a hurried mission to rescue one person? How quick and easy would it be to find a pilot with Cooper's skills, willing to risk his life and abandon his family? NASA's purpose is to find a new world to inhabit, and a follow-up exploration mission to Edmonson's planet may indeed be in preparation. Meanwhile, Cooper has to wait to see his daughter, and it's an essential plot point that his first commitment is not to leave her again - until she gives him permission to do so, because now she has family of her own to care for, and to be cared for. He goes on his own because he's driven by his emotional attachment to Brand, which trumps NASA's more logical, calculated approach to exploration.

The crew are sent spaceward to rendezvous with spaceship Endurance atop a very large rocket booster, very much like a gigantic Saturn 5. Once they traverse the wormhole and commence exploration, they ferry themselves from orbit to each planet's surface and back again aboard rather small single-stage vehicles. If each ferry vehicle is that capable, then why did they need the huge Saturn-type rocket just to get them to Endurance?

Correction: It could simply be to conserve fuel. They didn't have enough fuel to visit every potentially habitable planet so they would take whatever measures they could to ensure that the smaller vehicles had as much fuel as possible.

Phaneron

SPOILER The movie unveils that future-Cooper sent his daughter and himself the coordinates and tips on how to get to Nasa's secret camp. This creates a paradox, for it implies that only future-Cooper knew the way to teach present-Cooper, thus creating a loop. There must have been a first time-Cooper that got to Nasa's secret camp by drawing his own conclusions or after someone called, yet the movie's plot ignores it and creates a plot hole. While he gets the coordinates from TARS, he had to know there was a NASA base to ask TARS in the first place.

Sacha

Correction: This is not an error, it is simply the plot of the film. It is stated that it is a self-fulfilling series of events and that it was a loop.

Murph sneaks into Cooper's truck to get to NASA. Once Cooper closes the vehicle door after placing some blankets into it, a boom mic can be seen in the left wing mirror.
