Invites you to a lecture on

Nightfall: An Asimov Tribute or How I made it into Wikipedia

Abstract: Nightfall is usually considered to be the best science fiction short story ever written. It is set on the planet Lagash in a system with 5 suns. As a result, there is never any darkness except for one day every 2049 years when a combination of planetary motions results in darkness covering the entire planet. Civilization collapses in fire and has to be built again from scratch. Asimov, himself, did not worry about whether the system was possible or not as his focus was on the sociology of such a system.

Kepler has now found an incredible variety of worlds including worlds with 5 suns and I decided to look at the characteristics of such a system and to flesh out the physical details. We made this into a summer project with a student, wrote up the work and put it on ArXiv. Surprisingly, it turned out to be the most popular thing I’ve ever done. I will describe the background to the story, the context and the work we did.
