Like i understand there isn’t a lot of things for the heat from Stars to bounce off of but what causes Space itself to be cold? Is it naturally always cold and if so why?
In: Planetary Science
Heat is transfered via infrared radiation. However it needs matter to absorb heat and matter is very scarsed. Emptiness by itself has nothing to produce heat and thus it is cold.
If we look at individual onjects then depending on their position they may absorb a lot of infrared radiation. Eg space stations are very hot on one side and very cold on other.
