Re: Why is Space a Vacuum
Being in a vacuum makes the gasses and liquids diffuse through your skin rather rapidly. They do have a massive number of pores, which are just holes, after all. http://forum.shrapnelgames.com/images/icons/icon12.gif You will not explode or anything, but you will not Last as long as just being under water.

Your skin doesn't difuse liquids very rapidly at all. And your pores aren't simply holes in the skin. They are the external openings of your sweat glands. They don't diffuse any liquids under normal circumstances expect what is in your sweat glands. The vacuum of space isn't normal circumstances, but it's not going to suck your blood out your pores or anything like that. |
Re: Why is Space a Vacuum
in one of the short stories i read, people evacuated from one ship in space to another after expelling air from their lungs. no-one was in space more than 30 seconds. feasible?
side note: the book mentioned a technique where you breath heavily a few times then expell the air from your lungs. i tried this and was able to hold my breath for 20 seconds at the start and after some practice, 35 seconds. it really is easier, despite sounding counter-productive. |

Geo... your skin will also rupture with many tiny holes as the molecules inside your body attempt to diffuse from areas of very high concentration to areas of 0 concentration. Skin is a very weak barrier. It is, at best, no better than going from high pressure to low pressure. Of course, it is exactly the same as divers coming up from high pressure to low pressure...

Re: Why is Space a Vacuum
The reason the damage isn't as extreme as in going from depth is that the pressure difference as said isn't that big. Go down 38 feet into water..congradulations, you've just doubled the pressure. Going from here to the surface is very similar to going from the surface to space.
It's not going to be a pleasurable experience, but Fyron is exaggerating. "If you don't try to hold your breath, exposure to space for half a minute or so is unlikely to produce permanent injury." This is confirmed with experimental animals. http://imagine.gsfc.nasa.gov/docs/as...rs/970603.html |

Some more literature to edify you...

Long term a body in a vacuum would be desicated, that's why food is often vacuum packed. But it doesn't happen that fast, certainly not as fast as you are going to asphyxiate anyway. |
