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