Someone has created a simulation that details what would happen to a human in space without a spacesuit - and it's quite disturbing.
In this very graphic video, posted by DG EYE science on YouTube, they explain exactly what you can expect should a situation ever occur - not that you might have a trip to space this weekend or anything like that:
Going to space already seems like a daunting enough task on its own, but the risks involved in the trip make it incredibly difficult too.

If you were to be floating about in the abyss of outer space and you somehow lost your spacesuit, it wouldn't be good news.
Spoiler though: You wouldn't react in the way that is often depicted in Hollywood films.
The video introduces the scenario by highlighting this, saying that you 'surprisingly' wouldn't explode as science doesn't work that way, despite how gory and epic it may look like on the big screen.
What would actually happen in the first few seconds is - due to essentially being in a vacuum - the gases in your body would begin to expand, with the air in your lungs causing your 'lung tissue to rupture'.
Good start then.
Within five seconds, 'water on the surface of your eyes, skin and mouth' would evaporate.
Water in your body would then begin to boil as parts of your body start to enlarge.
We're only two-thirds water anyway.
Don't worry though, as the elasticity of skin is strong enough to withstand the increase in pressure from your insides.
The video states that 'your blood holds enough oxygen' for around 15 seconds of brain activity - though following this period, you would black out.
90 seconds after that, your heart will slow down and eventually stop, disabling your brain.
That's not it yet, because 90 seconds after that, you will finally die from asphyxiation, again dispelling the myth that you would instantly freeze as there is no atmosphere in space.
Dr. Kris Lehnhardt, element scientist for the Human Research Program at NASA, told Live Science: "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."
An aerospace engineer at NASA named Jim LeBlanc actually came close to experiencing this.
While testing the performance of spacesuits in a vacuum chamber in 1966, the hose which supplied pressurised air into his suit was disconnected.
LeBlanc explained in the documentary series, Moon Machines: "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."
Well, if you've heard all of this and still aspire to visit the depths of space, good luck to you.
