- The moment I'm exposed to the vacuum of space, my body would not inflate and explode, no, the body is a very nicely contained system. But those parts of me that aren't well contained, they'll be the first to go. The air in my lungs and digestive tract would quickly rush out. Moist, soft tissues will rapidly lose water, my mouth and lips and eyes would dry out and swell, as water was pulled to the surface of these things it would vaporise, and the decrease in it's pressure would cool my mouth and eyes to near freezing. My body would inflate to about twice it's normal size as gases in my blood came out of solution, slowly evaporating away, cooling the surface of my skin. Oh, and the blood vessels in my eyes would likely burst, spilling blood into my eyes, which along with all the other fluid in my eyes, would be rapidly vaporising on the surface and freezing and drying them out. Within about 15 seconds, I would go unconscious, because oxygen wasn't reaching my brain. And as far as I'm concerned that would be the end of the entire ordeal. For another 90 seconds or so, I would still technically be alive, but I wouldn't be aware of it or remember any of it. My dead body would remain internally quite warm for a while, because in the near vacuum of space there isn't much matter to conduct or convect heat away from me. Instead, I would really only lose heat through radiation, a much less efficient method. It would take hours for me to cool down to the temperature of space, and by then, I would be nothing more than a piece of slightly bloated and stretched piece of desiccated human beef jerky. if I was exposed to the sun's full on radiation, not filtered by the usual atmosphere of Earth, I would be a grossly sunburnt human beef jerky. In case that makes you hungry, let me give you some nutritional facts. 200 pounds of human meat in outer space would eventually become about 120 pounds of freeze dried jerky, and given what would be left of me that would be edible, as a snack, I'd be worth about 115,000 calories.
