41 ** CAUSE A NOVA TO OCCUR
43 ** A nova occurs. It is the result of having a star hit with
44 ** a photon torpedo. There are several things which may happen.
45 ** The star may not be affected. It may go nova. It may turn
46 ** into a black hole. Any (yummy) it may go supernova.
48 ** Stars that go nova cause stars which surround them to undergo
49 ** the same probabilistic process. Klingons next to them are
50 ** destroyed. And if the starship is next to it, it gets zapped.
51 ** If the zap is too much, it gets destroyed.
