    The sun is Illuminati propaganda.

    Aha! Space isn't really hot or cold because it's space. Matter has the property of being hot or cold. There's matter spread very thinly through space and the average temperature of that is very very cold, I guess because most of it isn't very close to a star? But the outside of the space station can be ridiculously hot when the sun shines on it. The thing is, there's no atmosphere in space to conduct heat around, so you only get heated when and while you're in direct sunlight.

    If you're already warm, vacuum is a great insulator (like double-glazed windows or a Thermos). You wouldn't immediately freeze in space if you suddenly fell out of an airlock because you'd lose your body heat slowly.

    I have got one query about space: if you floated about in it and you removed your helmet, would your head explode? :eek:

    It apparently wouldn't. It's one of those myths that have been in so many sci-fi movies that it's become accepted wisdom.

    I believe you would just suffocate. 'Just' being a strange word to include in that sentence, I know.

    Are you planning on floating around in space anytime soon then?

    Hahah I was just about to ask that. She seemed very relieved about this like her head exploding in space is a big upcoming concern.

    You can actually survive surprisingly well in space, unprotected, for a short time.

    I've never seen 2001: A Space Odyssey, but I think there's a scene where the main character does a brief "space walk" without his suit or helmet, unharmed. This is more realistic than instantaneous freezing or exploding heads.

    My understanding is you die of asphyxiation before the pressure kills you. And the pressure wouldn't cause your head to explode, it'd just gradually squash your head, making you bleed out of your orifices till you had some kind of anyerism.

    That would only be if the environment you were in was pressurized to begin with right? Like when you open the door on a plane? It for sure wouldn't be good but you wouldn't freeze over or explode or anything.

    I believe so. This means if you ever are out on a space-walk and you accidently sneeze, you can quickly hold your breath, remove your helmet - give the inside a good wipe - pop the helmet back on and then cheerfully carry on with your space-duties without having a big greenie in your peripheral vision the entire time.

    This has always been quite a comforting thought to me.
