   If a human is exposed to raw space vacuum, they will not freeze any time soon. Vacuum is an excellent insulator, because there is no matter that can transport away your heat (convection), like in an atmosphere or liquid. Managing heat is actually a problem in space, especially with sunlight.

   Rapid evaporation may cause cooling in certain parts of the body though.

   Latest episode of Star Trek: SNW got this wrong, so has a lot of other shows, movies and books in the past.

     @kwantumkraut @veronica I suspect another comparison to diving is the issue with sudden pressure drop: whether you go back to the sea surface or go from 1 atm to the void, too steep a pressure drop may cause gasses in the blood to form bubbles and cause damage.

     So maybe a spationaut might need to be exposed to progressive pressure lowering before going into the void out of a suit (but with ox)

     And a void exposure survivor would possibly need to be put in a pressurized chamber for a while.

     @veronica For some reason I was more concerned about being ripped apart by the space vacuum but apparently that’s not a problem either.

     @kwantumkraut @veronica Of course then I had to look it up:

     @strangeseawolf @veronica How about a heat exchanger that would radiate it as infrared photons? Those can travel in vacuum. Now don't ask me how the internals of that thing would work. 🤡

     @veronica Yeah, I originally had crew members threatened with freezing to death in one part of the ship in my WiP but changed it around to overheating because of that. In general, temperature management became a problem.

     @strangeseawolf @veronica Well, there's always the occasional asteroid to pass close by and rip away the ship's massive IR radiators... 😇

     @aaribaud @veronica Ha, I like that! But the ship is an intentional design nightmare, anyway, so it even fit the plot they had trouble with that.😂
