ELI5: why is it freezing in space if there is no matter in the vacuum to transfer body heat into?
gpt
Heat can be transferred two basic ways.  One is conduction, like when your body is in contact with cold air. As you realize, you need something to conduct the heat *to* for this to work.  
    
The other mechanism is radiation.  Your body is constantly radiating infrared light, carrying away heat energy.  (This is known as "black body radiation".) Black body radiation isn't all that fast, so freezing in outer space will take a bit of time. 
   
All objects that have a temperature above absolute zero will emit black body radiation, so this process will eventually freeze you, probably after you've died from some other issue like running out of oxygen to breathe.
