What would it feel like if you went from a room at ordinary room temperature into an adjacent room that was at the temperature absolute zero?
Would you be able to stay self-aware in that room long enough to feel the temperature if you were wearing indoor clothes, or would you die immediately?

Also, what kind of clothes would you need to wear in order to be able to stay in that room for maybe 5-10 minutes without any long-term damage?

I imagine that it would probably feel kind of like jumping into an ice hole, followed by intense pain and then a loss of consciousness about 4-5 seconds later.

It wouldn't be instantaneous because heat still needs to transfer out of the body before it is radiated away. You may not feel anything though because the nerve endings in the exposed skin would probably freeze up quickly. I'd guess you'd feel yourself quickly being unable to move, then you'd go blind, and soon transit to unconsciousness before ice crystals destroy every cell in your body.


I'm not sure any clothing material could survive absolute zero unless it is being actively heated.

I believe the shock would render you almost instantly unconscious, you might be "aware" for just a little more time than someone who was blown to bits by a bomb they didn't know was there. (and at that temp, any gas is going to be a liquid, maybe solid, so you'd be dumping them into a vat and maybe have to have at least something above absolute zero..)


Here's an interesting tangent though, what about the vacuum and extreme cold of outer space, would you feel very cold?


No, you would actually be initially hot.


(and not because your blood "boiled.")


It's because there is no air for convection to remove heat from your body...


Thx

It would freeze and kill you instantly. Same as if you were dipped into liquid nitrogen.

Gas and liquid have different conduction rates, so it isn't the same at all. A better analogy is being exposed to the vacuum of space.
