Quote from knjFuck it, just saw Gravity in 3d and this movie is MUST SEE in 3d. Great pictures, great tension, great soundtrack (if you can call it that way) anyway, great audio. I felt like i was up there in space for 90 min, great expirience !
Here's a link to your question, I was also very interested. I was questioning myself, what the feeling would be like.http://science.howstuffworks.com/question540.htm Basically you would die from asphyxiation if you were there for too long. However, you can survive in space for a short period of time with very little effects. (30 seconds to 2 minutes if you can hold your breath for that long)This is assuming you would go through slow depressurization methods like a pressure chamber, if not, I would assume sudden depressurization would severely harm your body, since space is a vacuum therefor there's no pressure?I remember reading once about a deep sea scuba diver that ascended hundreds of meters in a couple mere seconds due to an accident with his O2 can, he went into a coma and his body needed years to recover, although I don't think he ever recovered in full, I wish I had the link to that article. Anyway, same principles apply, pressure/depressurize is very important, because space is a vacuum. Apparently a space suit started leaking a few years ago ... before the guy lost consciousness he remembers the saliva in his mouth started to boil. That confirms what the article says about your body fluids starting to boil after a while.
