I took the theme of maritime disasters for my main, most recognizable one was the RMS Titanic. My Science has the Hindenburg (Yes it was an air ship, so it counts) Lindy's Revenge is an inherited nickname among my family and deals with last name and right of succession. My grandfather was Lindy, My dad was Lindy Jr. My sister took Lindy III but I loved Lindy's Revenge so I wasn't too upset even though technically I'm the heir to the name. My Klingon ship is Ghetto Klingon for "Where is the bathroom?"
Judging from some of the shipname origin descriptions there seems to be an unusual high rate of rather zealous people playing a game that is set in a universe were science has completely overthrown religion...
Not completely overthrown...just recognized it for what it is--mythology. A metaphor for the human spirit and our striving for that which is greater than we are, like the stars. The Daedalus Project doesn't denote the actual spiritual significance that the Greek stories about him may have once contained, just the metaphorical emphasis on science and technology that runs through his stories.
Cultures are defined by the stories they tell themselves. It was no accident that the Greek and Roman gods became associated with planets, moons, and constellations (in Western Civilization). Then they became further entrenched by Earth space exploration (Mercury, Apollo, Gemini, etc). It's ongoing.
