Comment on Space

The pressure isnt violently different (it’s only 1atm. Scuba divers can go up to 70atm with special breathing equipment). The issue is the boiling point of water is very low at that pressure, but on a cellular level the physics of that are going to be different.

Also space being “cold” is a bit of a misconception. Your body produces heat constantly, and it’s hard to dissipate heat in space, since you can basically only radiate it out as infrared light, which is a much slower process than being in physical contact with something.

In fact, we use vacuum chambers to insulate things such as in those metal thermoses that they tell you not to put in the dishwasher.

So being in space would actually be more like being wrapped in the thickest possible blanket than being cold.

i love hitting people with the heat dissipation fact. it’s measurably cold, but if you were out there with no protection you would get quite hot!

  So if i just get brakes into space, and we ignore dying from oxygen deprivation, could I die of overheating?

    Let’s pretend your spherical cow had a blood oxygenating machine implanted where its lungs go because it’s just lungs.

  How many minutes would Elon survive if strapped to the nose cone of a SpaceX rocket sitting in a ducktaped lawnchair wearing a Hawaiian Shirt and shorts and flipflops?

    5-10 idk how fast the rockets ascend, but I’d wager after that time he’d be doing pretty poorly…
    
    Earths atmosphere is cold, and the rocket is probably too slow to get heated by friction significantly.
    
    And Theres little oxygen up there.

    Isn’t it also hot? Like, I swear I didn’t make up the word thermosphere

That does make since, but would the lower boiling temperature of water not cool you down at least for a while? It takes energy for water to convert from liquid to gas, and I imagine in space that energy would come from you.

Can’t we use a spare billionaire or two to get some experimental data?
