What Happens if Your Body is Exposed to the Vacuum of Space? [Space]
posted January 14 2013 22:18.12 by Giorgos Lazaridis

Its so funny... Most people grew up believing that if they find themselves exposed to the vacuum of space, their bodies will explode due to negative pressure, their blood will boil due to decreased boiling point of liquids, and that they instantly freeze to death. Well, these three scenarios are... wrong, wrong and... wrong. The body will not explode, the blood will not boil, and (yes, true) no one will freeze to death.
- The body will not explode because there is no internal pressure whatsoever or something to cause it to explode
- The blood will not boil because it will not be exposed to the vacuum of space, since the body will not explode :D
- And curiously enough, the body will not freeze to death. Although we're talking about temperatures close to absolute zero (that's -273,15oC), there is no air or anything else to absorb the body heat! Yes indeed! You'll be hanging out there in -270oC and you won't even wear a sweater!

Watch the video to see if eventually the vacuum of space is lethal...
