   the astronaut in question is flash frozen, his blood freeze dried   
   instantly, assuming the astronaut in question didn't explode immediately   
   from the air pressure difference. This is not a really fun experiment.   
   Don't try this at home, kids.   
      
   The reason heat does not travel easily through a vaccuum is because heat   
   is kinetic energy, which operates at a much higher collective density   
   per cubic environment variable than in outer space. Consider the fact   
   that in outer space, the closest atoms are together is about a meter   
   apart, no accounting for dust and debris say in a ring like around   
   Saturn or an asteroid belt, whereas on Earth the atoms are much closer   
   together, say anywhere from a nanometer on up(that's 1/1,000,000 of one   
   meter). You can feel heat on earth because there are more atoms to   
   transmit heat than there are in space. Got it? Good. Since kinetic   
   energy is an active force, the less there is around it to support the   
   force exerted, the less force can be exerted and the more force must be   
   exerted to maintain equilibrium. It is a recursively dynamic equation   
   bearing on that which can be used efficiently for kinetic support   
   grounded to the base state of consumption rate needed to maintain the   
   ground state.   
      
   Is your question leading somewhere?
