The error of Guardians of the Galaxy Vol. 3 according to science
In an interview for Vanity Fair (via Comic Book), the retired astronaut discussed some of the scientific problems he encounters in some of Hollywood’s biggest blockbusters. Among them, Guardians of the Galaxy Vol. 3 – 85% by James Gunn, a film of which Peter Quill’s (Chris Pratt) jump into space at the end of the film stood out.
Hadfield commented that this scene was only partially accurate:
Our best guess is that you can live outside a spaceship without a suit for 30 seconds, really no problem, but beyond a minute and a half, things will happen to you that will cause irreversible and fatal damage; 90 seconds and you are a satellite (…) In about 15 seconds, all the oxygen in the blood will have passed through the lungs in the opposite direction and you will have exhaled it. In about 15 seconds, you will have blood without enough oxygen and when it rises to your brain, you will be unconscious.

One element that was almost right was Quill’s swelling and he gave some details about it:
If you took off your helmet in space, sure your lungs would collapse, but your blood would also bubble like if you opened a can of Coca-Cola where you release the pressure and suddenly there are bubbles in your blood, in your cheeks, and all over your flesh. , so you’re going to swell, but not as much as he does here (…) Suddenly he has frost on his face, and that wouldn’t happen like that. There is no water on the face, it will not freeze instantly. You have a lot of thermal mass, and it’s like shoving a big roast in your face. The freezer. It doesn’t freeze instantly, it takes a while. Most of the things happen inside the body, but it’s really difficult to show it to the movie audience.
