Heat is simply the motion of atoms: Something feels hot because you sense the frenzied movement of those little critters. At 98.6 degrees all your body's atoms are jiggling at about 1,000 miles per hour. Atoms stop moving only at 460 degrees farhenheit below zero. Since nothing can go any slower than "stopped," this is indeed the coldest possible temperature -- Absolute Zero.
