** 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.
