I'm one of the mis-taught.  I thought that conserved quantites (energy)
had some significatly different properties than non-conserved quantities
(velocity.)  If energy in a closed system is constant, and the universe is
a closed system, yet energy within it is not constant, then it sounds like
energy is not a conserved quantity (except perhaps within SMALL closed
systems.)
