In space would the human body expand to the point of death?

Question

it seems logical that it would. with no pressure being pushed down on the body what would stop atoms from spreading out. Just like as you increase pressure they compact.

Answer 1

yes, you would die before reaching space. the lower the presser the lower the boiling point. blood boils at body temperature at about 77,000 feet.

Answer 2

The Armstrong Limit is the altitude that produces an atmospheric pressure so low, that water boils at the normal surface temperature of the human body: 98.6°F (37°C) [1].

The altitude, also sometimes referred to as Armstrong's Line, is variously reported as being between 62,000 - 63,500 feet [2] [3]. At or above this point, exposed human fluids will boil without a pressure suit, and no amount of breathable oxygen, delivered by any means, will sustain life for more than a few minutes. A human would, eventually, boil in their own body fluids (a process known as ebullism), though death from asphyxiation would occur first, as the barrier of the skin and control of blood pressure would prevent blood from boiling immediately [4].

A NASA technical report, Rapid (Explosive) Decompression Emergencies in Pressure-Suited Subjects, discussing the brief accidental exposure of a human to near vacuum notes the likely result of exposure to pressures above the Armstrong Limit: "The subject later reported that ... his last conscious memory was of the water on his tongue beginning to boil." [5]

Answer 3

You wouldn't expand like enlarging, but you would explode, literally, from the pressure inside expanding out whatever paths of least resistence, those breaks it'd make in your flesh. Your blood vessels and internal organs would be doing most of the exploding.

I am unsure if this would happen before or after you froze.

Answer 4

The problem would be partly explosion due to internal body presseure, and partly all of the bodily fliuds would BOIL since the boiling point of liquids is low in low pressures. So, you'd rupture and then freeze-dry.

Answer 5

i think before the atom can expand, your body already explodes because of the pressure inside your body. That's why we need spacesuits.

Answer 6

No, atmospheric pressure is only 14 PSI. You would run out of oxygen in a vacuum, but you wouldn't pop.

Answer 7

You would die because of nitrogen bubbles forming in the bloodstream and cutting off oxygen to the brain.
Body would expand slightly.

Answer 8

i don´t tihnk that would happen that way. but i´m sure that the people will die from exanguination, from the boiling of the blood and explosion of the blood vessels, if they only had oxigen supply.

Answer 9

i think theyd freeze before they explode. space is like 2-3 K i think.

Answer 10

Actually, it would "exlode outward," the soft tissues like the eyeballs and such first.
