   Then the lowest "temperature" isn't zero energy? Ah, once more   
   "Zero Point Energy" rears it's ugly head. So is Quantum Mechanics   
   still "bunk"? Seems to me that if there is molecular energy   
   still available at 0 K, then that ISN'T the lowest possible   
   temperature! A TRUE "lowest temperature" would be when the   
   aether is frozen solid!
