Will People Explode in the Vacuum of Space
Space is a terrible, empty nothingness that’s out to explode our fragile bodies. It’s common knowledge that, when exposed to the vacuum of space, our blood will boil and our precious, pressurised internals will seek an exit from the nearest orifice.
The vacuum of space is deadly, there’s no doubt about that. But, actually, your connective tissues do an excellent job of holding everything in place and, thanks to your skin, neither will your blood boil; think about it – if that were the case then no one would be able to climb Everest or sky-dive and survive.
You won’t immediately freeze either because although the coldest parts of space are just above absolute zero (-273 degrees Celsius/-460 degrees Fahrenheit), there’s little matter to transfer your body heat away.
Exposure to intense UV radiation will cause serious sunburn too and without sufficient insulation, you will eventually succumb to the cold. Still, it’s nice to know that if someone does accidentally eject you from the airlock, you won’t pop like a balloon.
