A HORROR simulation has revealed what would happen to a human body in space without an astronaut suit.
The chilling video shows exactly what a person could expect if they were to be stripped of their spacesuits in the vastness of the universe.
The terrifying clip, created by the YouTube channel DG EYE, shows the human lungs bursting out and blood boiling in the far-from-ideal situation.
It explains that due to the absence of an atmosphere in space, water within our bodies would boil, turning from a liquid into a gas.
In the next five seconds, all the water in our body including on the surface of our eyes, skin and mouth would completely evaporate – and blood would start to boil.
Due to the pressure difference, all the gases in the human body would expand.
It could be seen in the simulation how the human body would swell up and become bigger because of the skin’s elasticity that would stretch and make room for the extra gas being formed.
And this would force the lung tissues to burst out.
Stefaan de Mey, senior expert at the European Space Agency said: “The oxygen starts expanding and rupturing your lungs, tearing them apart.
“This would cause boiling and bubbling of your blood, which immediately will cause embolism and have a fatal impact on your body.”
Without any external help, the human heart would eventually slow down and stop – and all the oxygen in the blood would be used up.
This would force the person to pass out immediately, causing death by Asphyxiation.
Dr. Kris Lehnhardt, element scientist for the Human Research Program at NASA said: “As you can imagine, given that 60 per cent of the human body is made up of water, this is a serious problem.
“In essence, all of your body tissues that contain water will start to expand.”
A human body without a space suit can only last between 1 to 15 seconds, before becoming unconscious due to lack of oxygen, experts have claimed.
Jim LeBlanc, an aerospace engineer at NASA, came close to this horror situation.
While testing the performance of spacesuits in a vacuum chamber, he stopped receiving pressurised air inside his suit due to a technical fault.
In the documentary series Moon Machine, LeBlanc explained that he started to feel the effects before he eventually blacked out.
“As I stumbled backwards, I could feel the saliva on my tongue starting to bubble just before I went unconscious, and that’s kind of the last thing I remember,” he added.
ACCORDING to NASA, a fully equipped spacesuit is a one-person aircraft - and is more than just a set of clothes that astronauts wear.
The specialised suits help the person inside from getting too hot or cold while also supplying fresh oxygen for astronauts to breathe as they work in the vacuum of space.
It maintains a safe pressure for the astronauts’ organs to function properly in space.
It also protects astronauts from small, dangerous bits of space that float around because of zero gravity.
Due to the lack of atmosphere, the sun rays are way more strong in space – and could severely damage the naked eye and exposed skin.
Space suits therefore protect the astronaut from the harmful rays of the sun, as well as other dangerous radiations in space.
