Granted: the water triple-point experiment gave cause for alarm. But it seems that the skin we were thoughtfully provided with breaks up that phenomenon so we don't boil off instantly.
Anything proceeding the "water triple-point experiment" comment made my eyes glaze over.
Perhaps if you have the time you can extrapolate?
All that I know is that if somebody was ejected into space, their lungs would proceed to protrude out of their mouth, among other things.
Perhaps that was due to my boyhood Sci-fi reading. It was entitled "The Cold Equation", and the story was about a girl who stowed away on a spaceship which only had enough fuel to accomodate the pilot and supplies required to get medication to a stranded colony on some planet.
She had snuck aboard to see her brother, she was discovered, and the pilot was trying everything he could to keep her aboard, but ultimately had to eject her because she was not part of the "equation" to get the ship from point A to point B.
