At the end of Guardians of the Galaxy 3, which was released in theaters earlier this year and is very popular with Marvel fans, like its two predecessors, Star-Lord finds himself in mid-space for a few seconds, without protection or combo. As he tries to join his friends by desperately jumping into the void.

Before he is saved by Adam Warlock (a new, nearly invincible character, but very important in the original comics), the space adventurer, played by Chris Pratt, instantly begins to freeze and his face suddenly swells.

A rather surprising physical reaction that might have excited the film’s audience. But beyond its visually spectacular aspect, is the sequence in question really realistic? Will this happen in real life? Not exactly, according to NASA astronaut Chris Hadfield, who was recently interviewed Vanity Fair.

“Our best estimate is that it’s possible to survive outside of a spaceship without clothing for 30 seconds with no problems. But after a minute and a half, some things will cause you permanent, irreversible, and fatal damage. After 90 seconds, you’re a satellite.”explained the now retired astronaut.

“In about 15 seconds, all the oxygen that’s in your blood will flow back into your lungs in the opposite direction, and you’ll breathe it out. So in 15 seconds, there’s no more oxygen in your blood, and when it hits your brain, you’ll lose consciousness.”

Therefore, it is quite an inappropriate situation. Especially when we add to that the significant swelling of the face, which is very similar to the one seen in the movie:

“We see that face swelling, it’s real”continues the astronaut. “If you take off your helmet in space, your lungs will kind of collapse, but your blood will also start to boil, like opening a can of Coke. Release the pressure and suddenly there will be bubbles in your blood, cheeks and all over your flesh. And you swell, but not as we see swelling here.’

According to Chris Hadfield, the creators of the Marvel feature film went a little overboard, especially with the frost that appears on the character’s face:

“It wouldn’t happen. You don’t get water on your face. It doesn’t freeze instantly. You have some thermal mass, it’s like putting a big roast in the freezer. It doesn’t freeze immediately, it takes a while. Most of it happens in your body, but it’s not easy to show to moviegoers, so they’re a little bit They exaggerated what was happening to his face.

This iconic sequence from the last part of the Guardians of the Galaxy, even if it is inspired by real information about the effects of a faceless spacewalk, is therefore heavily emphasized to offer the public a more impressive spectacle.
