How do people know that you can't breath in space? Has any1 even tried?

Answer 1

Oh ho! No one would dare. First of all there is no oxygen there, which is necessary for breathing and then there is no pressure in space to keep the body intact for trying. If someone would try to breath in space he would have to expose some part of his body to do so and then the consequences will be violent.

Answer 2

Scientists can determine the atmospheric composition of aother planet - say - Mars - by a techniquie called "spectroscopy" - which in its broadest sense is how matter interacts with light. Scientists can then determine from the light which elements are present and how much, Since oxygen has never been found then we know we cannot breath there. Also - oxygen is highly reactive - the only way you would ever get a stable amount of it in an atmosphere would be if it were constantly being replenished as it is lost due to reaction with so many things. About the only way to have an ongoing source of oxygen would be the presence of life - chemical reactions tend to destroy oxygen - not make it

Answer 3

Wow what a bunch of different ideas

We now know not to try breathing in space, but first we flew airplanes higher and higher and pilots either reported getting dizzy and lightheaded or even passed out. People studied the problem and realized that the lack of air was the problem.

Nobody has tried breathing at the altitude of the space station/shuttle because they know better. It has (as noted above) happened by accident.

Answer 4

When you were a little kid did you ever suck on your skin and it left a little mark... especially if you have very white skin you can see the reddish mark -- that's because when you were sucking you created a little bit of vacuum over the skin and the blood vessels in the skin burst. In space it would be a zillion times worse! The vacuum is MUCH stronger and would suck the blood right out through your skin, and out through your lungs... Your insides would pop out your mouth. If that sounds pretty gross, then you are getting the right idea.

How do we know there isnt air in space???.... because when you start at the surface of the earth and go upwards, the higher you go the less air there is! When you are up about six miles there is only about half as much air as down at the ground. And when you go up about 30 or 40 miles there is basically no air at all. So, in space, there is no air.

Answer 5

Please Goddess tell me that your age is in the single digits. Space is not an environment it is simply the name that we use to refer to the area not of earth.We know from those who have climbed the highest mountains that the higher you go the thinner the air. Early aerospace flights showed that oxygen requiring engines died out for lack of oxygen. We know that there is no air in space. We know from the hideous experiments performed by the Nazi "doctors" who placed prisoners in decompression chambers and removed the air that the prisoners died. I would, upon consideration, say that you can't breath in space. You also have to take into consideration that we live at the bottom of a sea of air. Our bodies are designed to work under that pressure. In space there is no pressure but our bodies will continue to push out against what it assumes is pushing in. This leads to an explosion of the body. So you either explode first or die of suffocation

Answer 6

Currently, there are 6.5 billion human beings breathing in space. If you are curious about space outside of Earth's atmosphere, you'd rather not try experimenting yourself. As mentioned in previous posts, humans need oxygen to breathe. 78.1% of our atmosphere is Nitrogen and is inert, while 20.9% is useable Oxygen. Oxygen, like all matter on Earth, is held close to the surface by gravity. The Earth spins, which helps moving gas particles escape away from Earth. As these particles spread out into a greater volume of space, the gas becomes less dense. Eventually, space becomes essentially devoid of oxygen for us to breathe and we asphyxiate. An example of asphyxiation at altitude would be an extreme skydiver; from miles up, they jump using oxygen tanks to stay alive. Otherwise, they'd die and fall to earth as a rather heavy projectile.

Answer 7

Yes, if I recall correctly, there was an early Russian Vostok space capsule that lost atmosphere, and the three cosmonauts came down dead. They tried to breathe vacuum and it didn't work.

Answer 8

The same way you know you can't breathe under water. You haven't tried that, have you?

Answer 9

If you believe the instruments that say there is no oxygen, then you can't breathe. If you don't believe, feel free to try it yourself.

Answer 10

Yes... people breath in space all the time. In fact, there are a dozen or so people up there doing it right now.
