How Can Space Be So Cold When the Sun Is So Hot?

Have you ever wondered how something can be scorching hot and freezing cold at the same time, separated by nothing but empty distance? The Sun's surface burns at over five thousand degrees Celsius, hot enough to vaporize almost anything instantly. Yet the space between the Sun and Earth, sits just a few degrees above absolute zero, the coldest temperature physically possible in the universe. There's no air, no wind, nothing to carry that heat across the void, and yet somehow sunlight still reaches us warm. So how does something so ferociously hot exist right next to something so brutally cold, with nothing in between to stop it? The answer comes down to a strange and fascinating truth about how heat actually travels, and once you understand it, you'll never look at a sunny day the same way again.
