So if I were in space and removed my helmet, would anything actually happen to me? You see it plenty of times in fiction where someones eyes might burst or their whole head may explode, but would anything really happen?

All I can think of that may happen is the air in your lungs would be sucked out and cause your lungs to collapse. But then again I'm pretty fucktarded when it comes to space.

[Anonymous No.1728508]

You would sufficate.

agreed

Yes, your eyes would pop out of your head, and you would suffocate as well. You will also freeze very very fast.

[Anonymous No.1728519]

The pressure difference is ~1atm, and yes, it is cold. But due to the lack of matter, your body heat can't transfer to colder matter.

You would sufficate before anything else.

[Anonymous No.1728524]

>You will also freeze very very fast
a near-vacuum is a piss poor heat conductor. cold would be the least of your worries.

[Anonymous No.1728525]

You would get a severe case of the bends. The bends is something thats caused by ascending too fast while scuba diving.

Think of a bottle of soda, its pressurized so all the gas stays dissolved in the liquid. When you open it, its depressurizes and the gas is released by fizzing lots of little bubbles. Basically thats what happens to your blood when you get the bends. And the air bubbles will start getting lodged in certain part of your blood stream. And when it gets real bad, they get lodged in parts of your brain, and you have a stroke.

So you never heard of photons, muons, neutrios? Or the other shit tons of exotic particles that are everywhere?

[Anonymous No.1728533]

you would have about 15 seconds to correct your situation until you start to get dizzy. after which point, all the fluid just below the surface of skin, lungs, and eyes will start to boil.

[Anonymous No.1728534]

>>1728525

I also read the vaccum will cause your lungs to work in reverse. Oxygen will start leaving your body through them as opposed to entering, and you end up suffocating even faster.

Although, I think the stroke brought on by air bubbles forming in your brain would get you first.

I remember seeing a scifi movie where they actually did an accurate portrayal (as far as i could tell, im not an expert) of what happens to you in a vaccum. I forgot what the movie was. I cant remember what it was, people were going crazy on the space ship though, and going in the airlock without a suit.

are you saying that in the absence of matter by which to conduct or convect heat away from the body, radiation will kick in? is that really what you're saying??

Haha, yeah I see this all the time. Where someone post something thats clearly not a troll post, but none the less, stupid fuck retarded, then it is shortly followed by a "Ha you got trolled"

probably the most realistic depiction of it ever to appear in film is in total recall.

in fact, i have even gone to the trouble of locating the relevant clip on youtube.

[Anonymous No.1728601]

uyour eyes won't pop out of your head, your lungs won't explode, and you won't immediately freeze. if you manage to re secure yourself within a minute or so (while still conscious), you will probably have severe lung damage and hypothermia.

heat actually transfers poorly in space, due to the lack of matter to transfer into.

[Anonymous No.1728604]

Your eyes won't pop out because you would freeze instantly...your hair would shatter off your head though

no, there is a reason why we use a vacuum as a thermal isolation ffs

This is probably a more realistic depiction of what would happen when exposed to the atmosphere of Jupiter, not Mars or the vacuum of space.

Chinese movie from the 80's - Men Behind the Sun

a movie about a japanese scientific team performing fatal endurance tests on live human subjects during WW2. The film was widely criticized for using real live cadavers. the clip I'm about to post is pretty upsetting as real dead bodies were used, in the middle of the clip, a scene is recreated where the scientists put a man in a decompression chamber and rendered it to a vacuum. You can see the cadavers entrails shoot out of his ass

in the magic school bus episode i watched, Arnold took his helmet off on Pluto. His head was immediately frozen into a block of ice, but, when thawed, he only had a really bad cold.

Now, I know Pluto is a planet and Im aware that the answer isnt exactly what you are looking for, but im relatively confident that this is similar to what would happen in the vacuum of space.

Watch the film "Sunshine" it has a realistic portrayal of surviving in a vacuum unprotected

Honestly, I'm not sure.

I would assume it's somewhere between coming out of a swimming pool and your lungs not being able to take pressure in that direction so they collapse. Everything else shouldn't be a problem, though. I guess your eyes might get pretty dry too.
I'm not sure about the whole eyes popping out bit, but there are people who can do that at will, so that doesn't even seem that dangerous.

Okay, you go into space through your airlock without a helmet.

The first thing your going to feel is probably the pressure in your lungs building up, if you hold it in, they're going to collapse and probably kill you. So you let out your breath.

Now you've been in space for about 5 seconds and so far it doesn't really seem too bad. Secretly, within your body nitrogen is beginning to form into bubbles within your blood stream, and parts of your body are beginning to swell up a little bit from the pressure, but it's nothing uncomfortable.

It's okay though, it's only been a few seconds, you can hold your breath for a minute, no problem. But holy crap, it's been 10 or 15 seconds now and what is that strange feeling on my tongue?

At this point you'll have lost consciousness. Your lungs are working in reverse expelling oxygen out of your body into the vacuum, the water on your tongue and eyes begins to boil and cool down those parts of the body [but probably not fast enough to freeze them] and you're completely unresponsive.

That's about what it's like. If someone gets oxygen into you within 2-5 minutes, you'll live with no serious injuries [unless you tried to hold your breath]. Past that, you're fucked.

You won't freeze until hours and hours after you've died. Metabolic processes within the body will keep you warm in space while you're alive, and residual heat in the body will take ages to slowly radiate away until the body is cold.

Now here's a video of a some NASA guy wearing a pressurized space suit in a hard vacuum when it springs a leak.

http://www.youtube.com/watch?v=KO8L9tKR4CY

Additionally, here's a NASA page explaining what happens when you enter a vacuum without a spacesuit, including references to animal testing.

Mucus membranes would spot-freeze causing significant damage. You would transiently experience a drop in temperature as moisture on the skin boiled off, but would then feel extremely warm and uncomfortable as you stop losing heat (like being in 100% humidity but worse)

All this is probably not noticed immediately due to the pain of sudden pressure change and the content of your lungs rapidly blowing out. Your blood will 'bubble out' slightly due to the bends, but not massively (skin can maintain a decent pressure by itself, and its a pressure diff of 1atm rather than several as it is in diving)


None of this is lethal, just extremely painful (once the shock is over, the ruined moist surfaces like eyes and inside the nose/lungs will be worst) and you will die of either oxygen starvation or severe overheating. I can't say which would be faster right now though.
