In 1941, science fiction giant Isaac Asimov wrote a short story called "Nightfall".
The story is about a planet called Lagash that exists in a system that contains six suns. The citizens of the planet never experience darkness, although through the story we find out that the planet does experience darkness every 2049 years. We also find out, because of the fictional scientists in the story, that civilization collapses every 2000 years. We are told about the existence of a doomsday cult whose core belief is that the planet will be destroyed in fire which occurs during the darkness.
