That's correct. He would eventually radiate away his body heat, but this would take a very long time, and if he were earth's distance from the sun, it's own radiation would pose a much larger threat to him. Greater even than that though is the lack of pressure, that would be what would kill you after a few minutes.

>>8698816
>If one was in space, hypothetically, without a space suit, would he freeze?
Yes. Eventually, long after he died of asphyxiation, he would indeed freeze, in all likelihood. Heat would still radiate away, and with no ambient pressure to prevent it, any exposed moisture would immediately flash-vaporize, carrying heat away with it. Now, the sun would also irradiate and warm his body, and eventually his body would settle at some equillibrium temperature, but if he's near Earth, or further from the Sun than that, the equilibrium grey-body temperature will likely be well below freezing.

>radiation is a larger threat than hypothermia
No. Not even smack in the middle of the Van Allen Belt. Hypothermia can kill in minutes; even high doses of radiation poisoning take hours to even show symptoms, let alone to kill.

If you're in the sun it can get very hot, if you're in the shade you will get very cold

one would likely lose a lot of heat through evaporation of water pulled out of pores by low pressure. ofc that would be a minor concern compared to depressurization, though ive read that people could actually survive on order of 10s in open space

>>8698816
You would die to suffocation first (you need energy to live, you need oxygen to convert energy to a form you can use)

If you had a gas mask, you would die to brain injury when the gas and liquids in your body would evaporate out from you (space has very near vacuum pressure); your brain would be deprived of oxygen and you would lose consciousness

If you had a gas mask and a suit that prevents gases from escaping but does not provide any insulation or heat, your body would lose heat by radiation, convection and conduction. In near-vacuum (=space) convection and conduction are so small compared to radiation, so almost all of the heat would be lost by radiation.
If you are 70 kg with a surface area of 2 m^2, with your limbs spread (so that radiation leaving them won't hit you back), with 37 degrees C body temperature, you would lose consciousness and then die to brain injury in 8 hours minutes when your body reaches 20 degrees C. You would actually survive for a little longer, because your metabolism produces heat.

You could also survive for a little longer too because Sun could heat you slightly.

>>8698816
correct, this also is the reason the sun doesn't give out any heat

Heat is a form of radiation (IR radiation), so though there is not anything for it to transfer to it can still be propagated into space.

God damn Maxwell cocksuckerfags.

>>8699397
space is not a true vacuum, and if you believe in space than how can you explain thermal radiation from the sun reaching earth if you believe space is a vacuum which nothing can propagate through?

aether confirmed

>>8698816
if space where real, hypothetically the astronaut would heat up and burn during the day due to the suns radiation.

>>8698816
>If one was in space, hypothetically, without a space suit, would he freeze?

Only very slowly. There is no medium to transfer your body heat to, you would only lose body heath through radiation. It would probably feel quite comfy temperature wise. Ignoring the excruciating pain obviously. You would die before you lose a significant amount of body heat.

Is one in sunlight? Is one in the shade?

If you are exposed to direct sunlight in Earth orbit, you will be heated more than slightly.

Fuck it, then, I am not going there.
