Terrifyingly 'realistic' simulation shows what would really happen to your body if you died in space

Ever wondered what would happen to you if you suddenly woke up to find yourself floating in space?

Spoiler alert - it would not end very well - but what actually happens to your body when there’s no atmosphere?

YouTuber Cleo Abram has done the hard work for us by explaining in gruesome detail just how we would die in outer space and it turns out that most sci-fi gets it completely wrong.

After a troubling simulation by SciScape that showed how a body would implode at 3,800m below sea level left viewers disturbed, this new clip of how a human body would die in space has not given us much peace of mind.

In the short video, Abram reveals that your first problem is the fact that there’s no atmosphere in space so the pressure difference between inside and outside your body would immediately cause all of the air to just rush out of you.

But don’t hold your breath, she warns, because then your lungs might explode.

Abram added: “In about 15 seconds, your brain would stop getting the leftover oxygen from your blood, so you'd black out. It's probably good, because your body would be swelling up, since the lower pressure would start to lower the boiling point of the water inside of your blood and tissues, turning it to vapor inside you.

“Your next problem is going to be temperature, because there's no atmosphere, there's no ambient temperature around you.

“But if you were in the sun, the light would make that side of your body heat up to potentially 150 degrees celsius, while simultaneously, the other side of your body would be slowly freezing down to negative 150 degrees.”

If you somehow manage to survive all of that happening to your body, you would be getting so blasted by radiation that it would probably poison you and give you cancer.

Just to add to the torture, eventually you might get shredded to bits by flying objects.

This left viewers reeling at the thought of being left to die in space, with one commenter writing under the video: “new fear unlocked.”

Another shocked fan of the channel added: “Being set ablaze while freezing would be a horrifying experience.”

Meanwhile another person joked: “Props to the person that tested this.”

Rest assured, no one has actually tested this theory out but it sure would be a gruesome way to go.
