I was once given a question in the popular quiz-show game, You Don't Know Jack, that went something like:
You find yourself suddenly ejected into space. Which of these gruesome things happens first?
- Your blood would boil
- Your eyes would explode
- You'd freeze to death
- You'd suffocate
The answer was 1. (followed shortly by 2.), because the drop in pressure reduces the boiling-point of the blood. They are usually pretty good about checking their facts, so I trusted this as a fact, until today.
On this thread, the top-rated comment states that this isn't true, and gives a plausable-sounding explanation for why.
So, which is it?
