What…. Space ain’t a total vacuum my dude. It is just a vacuum i. e. there ain’t no earth atmosphere in it.

Where there is energy there is temperature.

Hence space has temperature almost always above total zero though usually an unimaginably low magnitude above.

For example the closer you get to the sun the warmer since the more energy and stuff is in the vacuum. It is not like there is a hard cut or wall like barrier.

So the reason answers are contradictory is because space temperature is contradictory. It is not the same everywhere, at all.

Since people gather new information each day statements about an average change as well
