    Okay, thank you. I’m not a very smart man, and had always wondered how planets can be heated by the sun but not space itself. It never occurred to me it’s because of the vacuum of space that keeps it cold.

      Gotta have stuff to be heated. Nothing can’t be heated. But the energy that heats stuff can still pass through the space where the nothing is.
