The Petunia Effect is a galactic phenomena which occurs during the evacuation of an entire system.The effect sees ships equipped with a subspace engines suddenly receiving sentience, only to be suddenly destroyed. It is presumed that the effect is caused by too many subspace engines activating in proximity to one another.

Description
In the Cult of Prosperity Church-State sponsored thesis on the matter, the following description is given based on "Thorough Experimentation": "The ship gained sentience, hopes and dreams. Thought about finishing school, and raising a family one day maybe. But, as quickly as it learned to feel its body was extruded through an infinitesimally small hole in reality, turning them into a slurry of data that was then expunged from the server."
