How did they find out you can’t breathe in space?

Since there’s no air in space, there is no air pressure, so your internal hydrostatic pressure which normally prevents you from being crushed by the atmosphere actually blows you apart.

How many dead bodies are in space?

Lack of gravity can also cause body fluids to shift upwards, which may cause swelling, high-blood pressure and vision and organ problems.
