WHAT???  The speed of light in water is much less than the speed of light 
in a vacuum????  AAAUUUGHH!!  Einstein just rolled over!  I always thought:
'The speed of light is the same for all observers, no matter what his 
frame of reference'...  If what you say is true, then all kinds of phenomena
would open up simply by exceeding this 'slower' speed in water...  Eek!
