Human body in space WITHOUT a suit.. what would happen?
I've wondered for quite some time: if an astronaut were to remove his suit in outerspace, what exactly would happen?
Would the body explode or liquify due to lack of pressure and intense vacuum? Is it realistic for someone to breifly take off their helmet and then put it back on so they could temporarily feel the effects of space, or would death be immediate?

Well I've never seen it happen, but 1 atmosphere (about earth's atmospheric pressure) is 14.69 psi. Now that's 14.69 psi being pushed by your body outward. That doesn't seem as bad to me, but when you consider we have quite a bit of surface area, it adds up.
I think it's similar to what happens if you pull a deep sea ocean fish up to the surface really quickly, whatever that may be. My money's on boom. |

Rodney, thanks alot for the link. "And his last conscious memory was of the water on his tongue beginning to boil" is one of the coolest things I've read in a long time. Very fascinating information to me.

The movie "Event Horizon" seems to have a pretty accurate take on this exact thing.
Pretty good movie actually.

I guess Hollywood has to make dying in space more dramatic, if they applied real principles then it wouldn't be exciting (and gory) if it were similar to what that article implied. Respect science I do, but I gotta be entertained too...

the_marq, you could be remembering Alien: Resurrection where the final alien is killed by being sucked out through the hole. I suppose you could do some calculations to figure out exactly what the suction should be in that situation, but personally I was amazed at how much air they had apparently packed into that ship. :P

Alien: Resurrection sounds about right.
Seems to me that 14psi of pressure could be held in by simply placing my hand over the hole. Other than a nasty blister I'd probably come out of that disaster just fine.

In the link posted above (which definitively answers this question), the author writes that serious sunburn would be almost an immediate effect. Of course, that would depend on where you were in space without a suit. In the vast nothingness of the cosmos, radiation would be about the last thing you'd have to worry about.

The air in your lungs would EXPAND! This is what causes injury to scuba diver. At deeper depths, the air in your lungs is at a higher pressure. If you ascend, and hold your breath, the air will expand at the lower pressures near sea level. BOOM. If you don't hold your breath, and the air pressure equalizes, and the expanding air has somewhere to go. If you do a very rapid ascent while scuba diving, you can pretty much be exhaling for the whole journey up. Thats also why skin diving is safe. If you hold your breath and dive, you don't need to exhale, coz the original volume of air in your lungs at sea level remains the same. At depth, the air in your lungs just shrinks. |

That's odd. My physics teacher in high school said that you would indeed explode because of the "Equal or opposite reaction" law. According to his description, the Earth's atmosphere pressurizes our bodies, while our circulatory system reacts upon that pressure, pushing back. While the atmosphere and our circulatory actions are harmonius, once removed from the atmosphere, our circulatory system will STILL have that "depressurizing" effect, pushing outward, and without the atmosphere, there would be nothing to push inward.

No pertinent information, but I can't help but giggle when I read the phrase, "....and animal experiments confirm."
A group of astronauts all huddled around hurling gerbil after gerbil outside into space. I know that's probably not what happened. I'm sure it was much more scientific....you know, copius notes and all that. ![]()

Well, Spindles and Great White, as much as I love the Hitchhiker's Guide, I would have to say that holding your breath in this situation is a very bad idea, the pressure from your lungs would explode out of your throat if it just didn't blow out your chest.
Oh, and just as a nitpicky matter of point, Zaphod didn't pick up Arthur and Ford, that was done by the Heart of Gold alone due to the improbabilty field it created. Zaphod had nothing to do with it and even complained about it.

Ha... the Hichhikers Guide. Too bad Adams died after he wrote Mostly Harmless (or as I've heard it called, Mostly Awful.)
I've thought about it, and it reminds me of Titan A.E. Good movie. I wonder if persperation would boil off, or if it would burn when the water in your mouth boiled.
