Don't be mean. I promise to do my best to judge that fairly.

Space has no temperature. Space is a vacuum. Temperature needs things to jiggle.

Wonder how they calculated the "average" temperature. Was it weighted by mass or by volume?
Only mass-weighting really makes sense here imo
Wouldn't that be just star and not star?
No - it'd mostly be dark matter vs not dark matter.
I'm still on the "dark matter isn't real" train. It would be so unsatisfying if it was the answer.
Dark mind is definitely real though
Doesn't matter, it's just the eventual temperature of a black body kept in deep space
That's purely academic. IRL what actually matters is “how big and reflective is the thing you're in”.
You'd get real hot real fast in a matte black space suit.
Well yes, because space is not actually a complete vacuum.
But a thing in space is not a vacuum and is subject to heating via solar radiation
And actually, space only gets cold (more surface radiation cooling than solar heating) a bit after Mars orbit. On earth orbit, it's already a bit toasty.
Yeah, that's kinda why it's cold. Cold is just an absense of heat.
Cold is the absence of heat in a medium that can interact with temperature imo. It certainly wouldn't act like normal cold; if you stuck your hand out and felt the vaccuum, it wouldn't feel cold, and the heat in your hand would not flow outwards into space very much. There's no convection, only radiation. Space isn't cold, matter is cold, and there's no matter.
