It’s doesn’t make sense saying space is cold. There is no matter in space, so there is no temperature at all, it’s completely isolated. Of course, there is actually matter everywhere in space and that matter is cold, but there is so so little it doesn’t make sense to even consider it
“Hot” and “cold” in a conversational context is relative to the speaker. If the matter we’re talking about is your body, you’re gonna freeze (and other stuff). So yeah space is fucking cold.
You are not going to freeze because of the contact, you will freeze because your hot body is emitting light but unlike on earth, you won’t receive light back from your environment because there is no environment. You will end up sending all your energy out. If you were enbedded in a box with perfect mirrors around you, you would actually die from high temperatures
It’s more accurate to say that space doesn’t have a lot of easy access to external heat sources. Your local temperature is pretty much going to stay your local temperature without some significant effort being put into it. If you’re a rock, that’s cold. If you’re a spaceship full of humans and electronics that continually emit heat to operate, you’re going to stay pretty warm and shedding heat is an engineering problem that must be solved.
Sure, but unless you’re quite close to it and have the surface area of a planet, you’re not going to be catching a lot of that solar radiation. Some of the outer planets of our own solar system are very large, and very frozen, and unless you’re that big or bigger and that close or closer, so are you.
There’s an awful lot of space in between stars as well. So if you’re traveling anywhere, you’re spending a lot of time outside of ~10 AU from the nearest star. Solar radiation doesn’t play a big part out there.
i mean the main problem for most spacecraft, even unmanned ones, is cooling. not because of internal heat generation, but because there’s nothing blocking solar radiation from hitting them and nothing around them to convect that heat away.
Hm. Maybe you’re right then. I am both not an astrophysicist and am a bit stoned so I’m definitely willing to admit arguments here. I thought internal heat generation was the problem they were cooling far more than solar radiation but I could definitely be wrong.
On a Sci-Fi Star Wars spaceship though I think the internal heating is definitely going to be the bigger factor.

Cosmic microwave background radiation?
Matter and energy are equivalent after all.

probably! especially on the super-shiny kind they use in that movie.
