What would happen if someone took of their space suit in space?

Answer 1

1. all of the gasses in your body would collect and violently diffuse out of your body. Its kind of like getting the bends but a thousand times worse and a bit more explosive. you not only need air to breath but you need the pressure to be maintained outside to keep your insides inside. IOW you die within seconds.

2. if you are in a matterless part of space you would be susbjected to an immediate deep freeze. 0 Kelvin cold, like really, really, really cold. cold enough to slow your molecules to a crawl and then grind them to a halt.

2.5 if you are say near a nice friendly star you could be half baked, the part facing the star would be bombarded with a nice spectrum of stellar radiation and cooked at thousands if not millions of degree depending on how close you are. while the other side not faceing the star would remain frozen, in space no atmosphere, so molecules only move if there is an energy source to move them.

3. your corpse will float on in the world indefinately, breaking down very slowly over billions of years via contact with various matters and energies eventually being broken down to its base elements or even subatomic particles and becoming part of the creation of some star or planet of some other thing.

circle of life baby...

conclusion: you would die and become space dust.

Answer 2

If someone were to take off their space suit in space, the lack of pressure would cause their bodily fluids to vaporize, leading to swelling and a painful death from decompression sickness. The absence of oxygen would result in asphyxiation within seconds.
