What do you think would happen if you were exposed to the vacuum of outer space? (Please don't look it up)

You wouldn't implode or eyes pop out like in the movies.

It depends for how long.15-20 seconds, probably nothing. More than that? I'd die from freezing cold and lack of oxygen?

The cold wouldn't kill you. There isn't a medium in space to transfer the heat away from you.

I think bodily fluid would all boil out of pores. Good times.

Probably blow up like a balloon, then freeze.

All the moisture will be sucked out of your body and you will basically end up freeze dried. Real astronaut ice cream.

You would expand like a can of yellow spray foam and fill in all the cracks in the recent Congress Can Sell Anything idiot debt resolution plan.

I would go "What do I do - what do I do like Sandra Bullock in Gravity.

I would swell up like a balloon. If I tried to breathe I would blackout in seconds. Depending on where in space I was, I would either freeze or burn. Those are what come to mind right now.

You can actually last about 90 seconds

And I would want to pass out as fast as possible. I would be trying to breath.

I believe you would explode also. If going deep into the ocean would crush you, then space would do the opposite.

Praetorianus Fair enough.

The pressure difference between sea level and vacuum is one atmosphere, that's like going 10 meters or 33 feet down into the ocean. It won't crush you. Has anybody checked my link? We need better science ed.

I did some research and found, that after all the air in your lungs expel and the veins in your eyes would explode and you suffocate and die, you would most likely freeze-dry into a mummy like corpse.

Praetorianus Fair enough.
10/17/13 9:41 pm

I'd survive for a few minutes. I would DEFINITELY not explode as some think, and since my blood is contained, it wouldn't boil unless what of it is exposed due to an open wound. I'd freeze solid before I boil.

Nope. The only reason it doesn't boil in your veins right now is the air pressure of the earth's atmosphere. Your alveoli are not strong enough to contain your blood pressure without the help of the atmosphere.

Praetorianus Fair enough.

I've been a space buff since the first Moon landing. Now I looked it up, and this is NASA info. The pressure difference isn't enough. You lose ;)

Of course it's enough. I can boil water at room temperature in a syringe just by pulling on it, and that isn't even a complete vacuum.

When they talk about the body swelling to twice it's normal size, that is boiling.

The difference is that it isn't as lethal as it sounds. The blood does not boil off, it just boils. And it does boil in ALL of the tests and historic incidents.

And by the way, I've been a space buff all my life, and my information comes from an astronaut and from space program testing and accident data.

Praetorianus Fair enough.
10/17/13 10:23 pm

Since you insist, there's only one way to test it ;) I'd love to go to the ISS with you, go on an EVA and depressurize for about a minute. I wish we were a few decades in the future, we could place a bet on it :)

De-pressurizing for 15 seconds would do it. And we're not liable to remain conscious longer than that, so it might just end up a contest to see who could stay awake long enough to prank the other guy!

Your blood begins to boil after about 3 seconds. You get the bends and your body becomes one big bruise. Don't try voidwalking. It is no fun.

Your blood does not boil, it is not directly exposed to the vacuum and is part of an enclosed system. Your body will expand , but as long as you get pressure within 90 seconds you are fine.

Read in your own article where it talks of people and things swelling to twice their normal size. Liquids do not change volume like that in response to pressure. That is your blood boiling. It doesn't boil away. It doesn't kill you.

Doopy Remedial Americanism

But it does boil.

Remember, for example, how thin the alveoli in your lungs are. They cannot maintain the pressure required to keep water in a liquid state.

It's just not as lethal as it sounds.

The blood does not boil due to blood pressure.

"the vapor pressure of water at 37 C is 47 mm Hg. As long as you keep your blood-pressure above that (which you will unless you go deep into shock) your blood will not boil."

"My guess is that the body seems to regulate blood pressure as a gauge, rather than absolute pressure (e.g. your blood vessels don't collapse when you dive 10 feet into a pool)."
