it’s kindof neither.
Our normal sense of hot/cold is a measure of how hot the particles around us are. Space has so few particles, that whole paradigm breaks down.
Technically space is hot since temperature is a function of average particle movement and spaceborne particles are mostly moving stupid fast. Fortunately there are very few particles in any given volume of “empty” space so that translates to space being “cold”.
Probably a stupid question but how can it be cold if there’s no heat transfer?
