I see a lot of videos and shows where, if a person gets thrown out of an airlock, they immediately freeze to death. Disregarding the usual Hollywood exarcebation, WHY is space “cold” if the Sun generates so much heat radiation that it warms our very planet every day? Shouldn’t space be “warm”, then?
In: Physics
Just to note: those movie things where a person goes into space and freezes instantly are absolute cobblers. Even in the shade (which, as mentioned in other posts, *is* very cold) the only way you can lose heat in space is via radiation, since there’s no atmosphere to convect heat away, and radiation is a very slow process, especially at the sort of temperatures a human body is at. It would take hours in reality for you to freeze if you were in space–the more immediate lack of oxygen causing you to suffocate would be your primary problem.
