Question: How was Ryan able to swim after the capsule splashed down in the water? Isn't readjusting to earth's gravity pretty difficult when you've spent a long time in space?
Question: When Matt bounces, and Ryan doesn't bounce, they make the rope snap. Aren't tether ropes very difficult to snap in real life?
Question: When Ryan is descending back into the atmosphere in the Shenzhou, two pieces pop off the landing module after the big tracking shot. One appears to be part of the heat shield, and the other looks like an O-ring from the window. 1) If it really was a part of the heat shield, wouldn't she along with the Shenzhou have burnt up in the atmosphere and 2) If that was a part of the window, shouldn't it pop out due to the pressure differential? Or, if I'm wrong about those two parts, what are they?
Question: SPOILER: What part of Earth did Dr. Stone land on?
Question: Are Bullock's reactions to all the situations she encounters logical, considering she is a trained astronaut? For instance: she repeatedly noticed that she is running out of oxygen, but she still keeps talking, screaming and hyperventilating. The first thing you have to do is to get your breath under control, but she keep talking and screaming all the way... Would a person like Bullock get through all the NASA psychological tests?
Question: How would Stone have known where she would land? Was it just pure luck that she landed in water and not on land?
Question: During the scene in which Matt detaches himself from Ryan so that he does not pull her away with him, why didn't he bounce back towards her when the rope snapped taut? Was there something that kept pushing/pulling him away that I missed?
Question: On the Russian vessel, shortly after Ryan boards via the airlock, there's a readout in English concerning oxygen. Shouldn't the readout, and indeed virtually everything on that ship, be written in Russian?
