I don’t think water would boil in space. As a matter of fact I can’t even understand why it would turn to vapor, because there would be no medium for the vapor to disseminate. Nature has a tendency of concentrating into spheres. So if water were to be released in space, it would just turn into a glob of sort, and then gradually freeze, and the speed with which it would do so would be contingent on the size of the body of water (due to inertia right?). I don’t know if the sun’s radiation would even have any effect in heating it up. Can someone answer this question?

Second, all the calculators that I found with which someone can find the boiling point of water depending on pressure, would not calculate for Zero pressure. (pressure in space is Zero right?) The lowest they can measure the boiling point is for 0.03 Bar, at which water boils at 26 degrees Celsius. But Space is much colder than 26 degrees Celsius, right? So water would not boil in space. Moreover the article above first states that water on the tip of someone’s tongue (saliva) and in the eyes would boil, but a few lines later it says that it would freeze. I don’t get that part. Some people above say that water, and the body’s liquids for that matter, would boil because of the body’s, and thus their own, temperature, being around 36 degrees Celsius. Yet, isn’t the body contained inside skin? And in turn, blood into veins, cells into membranes, and so forth? Don’t these provide a kind of pressure-suit? If this idea holds, I understand swelling, but not exploding or imploding or blood boiling. Perhaps the pressure that the will be created inside the skin is enough for the body’s normal temperature 36-37 degrees to prevent the boiling of liquids, probably 0.6 Bar. I think skin can take that, right?

The other point is exhaling entirely before going into space without a suit…but wouldn’t that happen automatically? I mean, wouldn’t the air want to escape out of the body, so exhalation would just happen on its own, no matter how hard you tried to keep your breath? Or could you hold a breath? I still don’t quite understand why it would be harmful to hold your breath. Could someone elaborate? And why would someone have to keep their eyes closed? Why would the eyes want to pop out? Any trapped air can get out through the ear-larynx-nasal cavities. Another question is whether fluids can come out of the body’s pores. is that even possible?

Based on the article it seems that Zero pressure is much less harmful than a lot of pressure. People/tribes who live on very high altitudes have bigger lungs, compared to those who live near valleys, to account for lack of oxygen. What would the effect of inhaling denser air suddenly (from a cylinder container) be? And would these people be better candidates for such an experiment as releasing a person in an absolute vacuum in space?

I wonder if a pressure–boiling-point graph was made, whether it would curve towards infinity on either end, making it thus curve more acutely at more extreme pressure. If that’s the case, the lower the pressure the less heat would be required to boil water. But how many degrees Celsius are required to boil water at absolute Zero pressure? What puzzles me more is that it has been said that there are traces of ice on the moon and certainly they have found ice on asteroids. If so, why doesn’t the water on the moon and on asteroids turn to vapor, but instead remains solid ice? Neither of the two has an atmosphere nor would there be pressure on an asteroid, right? Just cold, hard vacuum. (the moon might have a tiny bit of an atmosphere though). But both are hit by the sun directly for long periods of time occasionally. Does he ice melt? I doubt it.

Last but not least, just as we can equalize for very high pressure when diving at great depths, can’t we equalize for a vacuum? I mean, granted it could take months, if not a years, but it is possible right? Then the only need one would have, would be for some kind of air mixture to breath and protection from radiation.

Why don’t we pay a someone to do this? Their family could use the money to build a statue of him and use the remainder to buy a Porsche. If one could volunteer for science, we would know for sure. We could even throw a monkey out there. Animal rights activists don’t even have a say, because if monkeys could travel in space, they would use humans for the same reason. I’d volunteer my dog, Rex, for this experiment.

and the movies were fake , about blowing up

ok, but you really do blow up

i see.

well, it takes 2 minutes ot blow up.

that’s not long. well wait a minute that s kinda like being under water.
so thats a nice way of seeing it, if you go under, you have to come back up for air. so, we can go into a little bit of open space and then back into a sealed chamber, and presss the airlock button, and its ok.

titan ae. the movie has a scene like that, they jump out into space and use the un,m fir extinguisehr thing, remember>?

go see that movie, its in the first 30 minutes of it
mike

basically what i imagined.

nice to know. haha

thats crazy. the near future, we can use this knowledge

yeah thats ..damn…. interesting,

Mission to Mars.

And the astronaut chick was a very Hot astronaut: Connie Nielsen.

I was wondering it that suddenly frozing would be possible, but I had a hope that there was a little amount of time before any damage could be caused to a human body.

My memory might not be exactly accurate, but that’s how I remember it. And I remember being fascinated! But after reading this article, I see that they were dead wrong. Yeesh!
