  14: **  CAUSE A NOVA TO OCCUR
  15: **
  16: **	A nova occurs.  It is the result of having a star hit with
  17: **	a photon torpedo.  There are several things which may happen.
  18: **	The star may not be affected.  It may go nova.  It may turn
  19: **	into a black hole.  Any (yummy) it may go supernova.
  20: **
  21: **	Stars that go nova cause stars which surround them to undergo
  22: **	the same probabilistic process.  Klingons next to them are
  23: **	destroyed.  And if the starship is next to it, it gets zapped.
  24: **	If the zap is too much, it gets destroyed.
