So, how does space kill you? I’m glad you asked. The main problem is pressure. There isn’t any. So, don’t hold your breath or your lungs will explode. Blood vessels rupture. Exposed areas swell. Fun fact! The boiling temperature of water is much lower in a vacuum. Which means that your sweat and your saliva will boil, as will the fluid around your eyes. You won’t notice any of this because fifteen seconds in, you’ve passed out as oxygen bubbles formed in your blood. And ninety seconds in, you’re dead. Any questions?
