Man blows up?
No, people do not explode, no matter how bright it is not shown in science fiction films. The fact they are fantastic – the laws of the genre oblige, but in reality, this does not happen with a man. It must be admitted that the logic of the myth is still there, as is logical to assume that because of the large pressure difference people “puff up” and can burst like a balloon.
In fact, people simply exhale all the air, as if a pressure drop in a spacesuit 1 atmosphere of the soft palate, the area of which can be conventionally considered for the 4 square centimeters, the load is 40 kilograms. A man with good intentions will not be able to contain the air. And, of course, it will not explode. Human tissue – is not an elastic balloon is not as brittle as twigs.
Contrary to a man, who turned out in space without a spacesuit, will not turn into a piece of ice, and will not immediately freeze because space – vacuum, not cold and not hot, heat is transferred only by radiation there, and the person is insignificant. The person will feel cool, and with a body, the surface will evaporate the water. Instant freezing a person is not exactly threatening – in the absence of atmospheric heat will be discharged from the body very slowly
The blood of the person caught in the space without a suit, boils accurately, because if the external pressure drops to zero for a blood pressure of 120/80 blood boiling temperature will be 46 degrees, and it is above body temperature. Blood, in contrast to the same saliva stored in a closed system, veins and vessels allow it to be in a liquid state even at low pressure.
Water, unlike the blood, begins to evaporate quickly, and from all surfaces of the body, including the eyes. Also, boiling the water in the soft tissues will cause an increase in certain organs and about twice as organ damage. It is also believed that a person being in vacuo symptoms may experience decompression sickness, but this is unlikely because the drop in pressure will be only about one atmosphere.
Come on – lights, but can scorch. In space, there is no protection from ultraviolet radiation. On all exposed areas of the body exposed to direct sunlight, ultraviolet burns appear.
Would the man suffocate? Yes, a person suffocates. After about 30 seconds he lost consciousness as the air, as we know, he will have to exhale, the person will experience a state of deep hypoxia. There will be a loss of orientation and vision.
However, if within one and a half minutes a person is still placed in an oxygen chamber, it is likely he will recover. In the history of astronautics were several precedents when people experienced the depressurization in the space.
19 august 1960 astronaut Dzhozef Kittinger made the jump from a height of 31,300 meters. Kittinger tightness right glove was broken, causing the hand badly swollen and painful. In 1965 an American astronaut was in the vacuum chamber, he lost consciousness in 14 seconds. He remembered that he had in the meantime boil saliva on the tongue.
