Real Astronaut Criticizes Guardians Of The Galaxy Vol. 3 Over Star Lord Scene

It’s no stretch to say that Star-Lord’s time in space looks incredibly painful, between the premature facial swelling and freezing. In the context of the film, it’s nothing short of a miracle that he survives, let alone recovers with seemingly no lasting health issues. This is another aspect of Star-Lord’s near-death experience in space that Chris Hadfield didn’t buy. He described in vivid detail what happens to the human body in space within a few seconds, making it clear that Star-Lord is lucky to have lived and escaped space without major health problems.

«90 seconds, and you’re a satellite. Within about 15 seconds, all the oxygen that is in your blood will have come through your lungs the other way, and you will have breathed it out. In about 15 seconds, you have blood without enough oxygen in it, and when it gets up to your brain, you’ll go unconscious,» he said, going on to state that the swelling comes from the blood in one’s body starting to «fizz like opening a can of Coke.» Without a helmet in space, one’s lungs would also quickly collapse.

With all of that in mind, Star-Lord should thank his lucky stars that the MCU’s avoidance of scientific accuracy didn’t bring his life to a gruesome end.
