…in what proximity would you have to be to the sun and how fast would you have to be spinning (like a rotisserie chicken) so that your light side didn’t burn and your dark side didn’t freeze; rotating just enough to keep a relatively stable temperature?
Absolutely absurd, I know but this question somehow popped into my head and won’t leave. 😆🐔🔥🧊
Interesting and does make sense. Where does this image of stuff freezing instantly as it “enters” space vacuum come from?
Moisture as any other fluid when exposed to vacuum of space expands and boils this transforms to vapour and that process absorbs energy which could cause the freezing.
Probably because many pop science articles will mention that the background radiation of the universe is at about 2-3 degrees above absolute zero. Plus things like the night side of mars being freezing, pluto being a frozen rock, comets being made of ice etc…
Depends on the entry I suppose. A liquid being sprayed out you’d imagine would do exactly that (assuming it’s not being heated by sunlight), but that’s probably because spraying means it’s a lot of tiny droplets, all with very little heat energy individually and lots of surface area to lose it. A big block of something like hot metal wouldn’t suddenly freeze, but cool as fast as its surfaces could radiate the internal heat.
This is going strictly as a thought experiment, the math or physics is probably different to some degree.
I think an additional effect is that, the drop in pressure causes any liquids exposed to it to vaporise, which is an exothermic process, and it’s a race to see whether it boils off entirely or the inner part freezes to solid from the drop in temperature through conduction. So the immediate surface of your body would either dry out or flash freeze but the inner part take a while to solidify.
Why there is any ice in space and it doesn’t just sublimate away over time I’m not sure.
What I had in mind was stuff like people getting shot into space in sci-fi, stuff like that. Theyre usually shown to freeze in the matter of seconds. So I guess thats unrealistic, though its a little sad because that means its a much more painful death by suffocation
Yes, that’s correct. Scenes like from Total Recall or Mission to Mars are totally wrong. It will be more like the opposite of drowning but about as bad. I’m trying to remember if The Expanse got it right in the several examples, they usually do pretty good hard science. It may have been a combination, since anyone seeing someone NOT freeze will say it looks fake.
